Top 13 'Better-Than-New' DIY Upgrades to install in Your Pre-Owned EV on a budget
Congratulations! You’ve made the savvy decision to purchase a pre-owned electric vehicle. You're saving money, reducing your carbon footprint, and getting to experience the instant torque and silent glide that makes driving an EV so addictive. But looking at your "new-to-you" car, you might be thinking: "How can I make this feel truly mine?"
Buying used doesn’t mean you have to settle for someone else’s scuffs, a dated look, or missing features. In fact, it presents a golden opportunity. With a fraction of the money you saved by buying pre-owned, you can install a few thoughtful, budget-friendly DIY upgrades that will not only personalize your ride but make it functionally better than it was when it first rolled off the factory line.
This isn't about bolting on massive spoilers or installing underglow (though, you do you!). It’s about smart, practical, and affordable enhancements that elevate your daily driving experience. From protecting your investment to adding modern conveniences, here are the top 13 'better-than-new' DIY upgrades to install in your pre-owned EV on a budget.
1. All-Weather Floor Mats: The Unsung Hero of Interior Protection
This might be the least glamorous upgrade on the list, but it's arguably the most important. The factory-standard carpeted floor mats are okay, but they are no match for muddy shoes, spilled coffee, or a child's dropped ice cream cone. A set of high-quality, laser-fitted all-weather floor mats is a non-negotiable first purchase.
These aren't your grandpa's floppy rubber mats. Modern options from brands like 3D MAXpider, WeatherTech, or TuxMat are custom-molded to the exact contours of your vehicle's floor pan. They feature high walls that contain spills and debris, preventing moisture from seeping into the carpet and causing mold, mildew, and corrosion. This single upgrade makes cleaning your interior a 30-second wipe-down instead of a 30-minute vacuum-and-scrub ordeal.
Pro Tip: Look for mats made from a rubberized thermoplastic material. It offers the durability of rubber without the unpleasant smell and provides a more premium, less "industrial" look. This is a simple upgrade that dramatically protects your car's resale value for a minimal upfront cost.
2. A Center Console Organizer: Tame the Chaos
Many EVs, especially earlier Tesla models and the Nissan Leaf, are notorious for having cavernous, deep center consoles that quickly become a black hole for sunglasses, charging cables, keys, and loose change. For under $20, you can purchase a drop-in organizer tray that instantly restores order and usability to this space.
These trays are typically molded to fit perfectly, creating a two-tiered storage system. You get a shallow, compartmentalized tray on top for frequently used items, while the larger space below remains accessible for bulkier things. It’s a five-second installation—you literally just drop it in—that will save you countless moments of frustratingly digging for your parking pass or chapstick.
Pro Tip: Some organizers even come with flocked lining to prevent items from rattling around, adding a touch of quiet luxury that even the original manufacturer overlooked. It's a small detail that makes a huge difference in day-to-day convenience.
3. DIY Ceramic Coating: Long-Term Shine and Protection
A professional ceramic coating application can cost upwards of a thousand dollars. But for the dedicated DIYer, a consumer-grade ceramic coating kit can be had for under $100 and offers 80% of the benefits for 10% of the price. This upgrade is more about investing your time than your money, but the results are spectacular.
A ceramic coating is a liquid polymer that creates a semi-permanent, hydrophobic (water-repelling) bond with your car's paint. This makes your EV incredibly easy to wash, as dirt and grime have a hard time sticking to the slick surface. It also provides a deep, glossy shine and offers superior protection against UV rays, bird droppings, and light scratches compared to a traditional wax.
Pro Tip: The key to a successful DIY ceramic coating is preparation. You must thoroughly wash, decontaminate (with a clay bar), and polish the paint to perfection before applying the coating. Watch several tutorials online, work in a shaded, clean area, and take your time. The weekend of effort will reward you with a year or more of protection and head-turning shine.
4. Upgraded LED Interior Lighting: See Your Cabin in a New Light
If your pre-owned EV came with dim, yellowish halogen bulbs in the cabin, dome lights, or trunk, this is one of the easiest and most impactful upgrades you can make. Swapping them out for crisp, bright white LED bulbs instantly modernizes the interior and makes it feel more premium and spacious.
LED replacement bulbs are inexpensive and available for nearly every common automotive socket. The process is usually as simple as prying off a plastic lens cover with a trim tool, pulling out the old bulb, and plugging in the new LED. The difference is, quite literally, night and day. Finding a dropped phone or item in a dark car becomes effortless.
Pro Tip: Pay attention to the color temperature of the LEDs you buy. A "Pure White" or "Cool White" (around 5000K-6000K) provides a modern, clean look without being overly blue or sterile.
5. A Quality Steering Wheel Wrap: Improve Your Touchpoint
The steering wheel is the part of your car you interact with most. If the one in your pre-owned EV is worn, shiny from oils, or made of a basic urethane, a high-quality wrap can completely transform your driving experience. This isn't a cheap, fuzzy cover from an auto parts store; this is a stitch-on wrap that looks and feels like a factory installation.
Companies offer kits made from genuine leather, Alcantara, or perforated materials, often with options for custom stitching colors. While it requires some patience to stitch on yourself (plan for a couple of hours), the result is a thicker, grippier, and far more luxurious-feeling wheel. It makes an older car feel brand new from the driver's seat.
Pro Tip: Take the steering wheel off the car to do the stitching. It's a few extra steps, but it makes getting a tight, professional-looking stitch a thousand times easier than trying to do it in the car.
6. Puddle Light Projectors: A Touch of Custom Flair
This is a fun, low-cost mod that adds a surprising "wow" factor. Many EVs come with simple lights on the bottom of the doors that illuminate the ground when you open them. You can easily swap these standard "puddle lights" with aftermarket projectors that display a logo or design on the ground.
The installation is a snap—literally. You use a small flathead screwdriver or trim tool to pop out the existing light housing, unplug it, plug in the new projector, and snap it back into place. It takes about one minute per door and requires zero wiring or electrical knowledge. It’s a small touch that makes your car feel uniquely yours every time you step out at night.
Pro Tip: You can find projectors for your car's brand logo or even custom options. Just be sure to buy a set that is specifically designed for your vehicle model to ensure a perfect fit.
7. Chrome Delete Vinyl Wrap: Modernize Your EV's Look
A design trend of the last decade was to adorn cars with chrome trim around the windows, on the grille, and on door handles. Today, a "blackout" or satin black look is far more contemporary. A "chrome delete" is the process of covering this shiny trim with black vinyl wrap, and it’s a fantastic DIY project.
You can buy pre-cut kits for popular EVs like the Tesla Model 3 or purchase a roll of 3M or Vvivid vinyl wrap and cut it yourself. It requires a heat gun, a squeegee, and a healthy dose of patience, but it's a very forgiving process for beginners. The vinyl can be lifted and reapplied if you make a mistake. This single aesthetic change can make a 5-year-old car look like it just rolled out of the showroom today.
Pro Tip: Start with the flattest, straightest piece of trim to get a feel for how the vinyl stretches and adheres before tackling more complex curves.
8. Mud Flaps: The Unsung Protector of Your Paint
EVs, with their often-smooth and aerodynamic body panels, are particularly susceptible to having road debris and rocks kicked up by the tires, chipping the paint along the rocker panels and rear bumper. A simple set of mud flaps is the most effective and affordable way to prevent this costly damage.
For many popular EV models, you can find no-drill mud flaps that install in minutes using the existing factory mounting points and push-clips. They are designed to blend in with the vehicle's styling while providing a crucial barrier against rocks, tar, and road salt. As my friend and mentor Goh Ling Yong often says, an ounce of prevention is worth a pound of cure, especially when it comes to your car's paint.
Pro Tip: Choose mud flaps made from a flexible but durable material. Rigid plastic can crack from impacts or in cold weather, while a more pliable material will absorb hits and last longer.
9. A Wireless Charging Pad or Mount: Ditch the Cables
If your pre-owned EV is a few years old, it may have come out just before wireless phone charging became a standard feature. You can easily and affordably rectify this. There are countless aftermarket solutions, from sleek pads that integrate perfectly into your center console to clever vent or dashboard mounts.
This upgrade cleans up your cabin by eliminating the need for messy charging cables snaking across your dashboard. Many console pads are designed to look like a factory part and simply plug into your car's existing USB ports for power. It’s a modern convenience that you'll appreciate every single time you get in the car.
Pro Tip: Make sure the charger you choose has a high enough wattage (10W or 15W) to effectively charge your modern smartphone, especially if you're using navigation apps while driving.
10. Sound Deadening Material: Achieve True EV Serenity
Electric vehicles are already exceptionally quiet, but that silence can sometimes accentuate road and wind noise that would be masked by a gasoline engine. Applying sound-deadening material, like butyl mats with an aluminum layer, to key areas of your car can elevate your cabin from quiet to serenely silent.
This is a more involved DIY project, but it's not overly difficult. Key areas to target are the inner door skins (which also improves your audio system's bass response), the floor of the trunk, and under the rear seats. The material is self-adhesive; you just cut it to size, peel, and stick, using a small roller to ensure good adhesion. The result is a significant reduction in road noise and a more solid, luxurious feeling when you close the doors.
Pro Tip: You don't need to cover 100% of a panel to get most of the benefit. Aiming for 25-50% coverage on a panel is often enough to damp the resonant frequencies and make a huge difference.
11. Automatic Frunk/Trunk Lift Struts: A Touch of Hands-Free Luxury
Here’s an upgrade that adds a feature typically found on high-end luxury vehicles. For many EVs, especially those from Tesla, you can purchase aftermarket gas struts that will automatically open your frunk (front trunk) or trunk all the way when you unlatch it via the app or key fob.
The installation involves replacing the stock support struts with these new, more powerful ones. It’s usually a simple matter of prying off a few retaining clips with a flathead screwdriver and snapping the new struts into place. It’s a 15-minute job that adds a delightful bit of "magic" and convenience, especially when you're approaching the car with your hands full.
Pro Tip: Some kits for the trunk also include a "soft-close" feature, which is an even more premium touch. Read reviews to ensure you're getting a reliable kit with the right amount of opening force.
12. An OBD2 Dongle and App: Your EV's Health Tracker
This is the ultimate tool for the data-loving used EV owner. An On-Board Diagnostics (OBD2) port is standard on almost all cars, and with a compatible Bluetooth or Wi-Fi dongle (costing around $30-$100), you can access a treasure trove of information about your vehicle.
Using a vehicle-specific app on your phone (like LeafSpy for the Nissan Leaf or ScanMyTesla for Teslas), you can monitor the real-time health of your high-voltage battery. You can see the state-of-health (SOH), individual cell voltages, battery temperatures, and charging history. This data is invaluable for understanding your battery's degradation and ensuring you're getting the range and performance you should be.
Pro Tip: Monitoring your battery's health is one of the most empowering things you can do as a used EV owner. Here at the Goh Ling Yong blog, we believe knowledge is power, and this tool gives you more knowledge about your car's most important component than even the dealer might have.
13. A Performance Pedal Set: For the Sporty Look and Feel
The stock rubber pedal covers on many cars are functional but bland. You can easily upgrade to a set of aluminum or stainless steel performance pedals for a sportier, more premium look in the driver's footwell. These typically have rubber inserts for grip and are designed to look like those found in high-performance vehicles.
Installation is straightforward. The brake pedal cover usually slips over the metal pedal, while the accelerator pedal cover often replaces the existing plastic piece. There's no drilling or complex work involved. It's a small, inexpensive cosmetic change, but it's one you'll see and feel every time you drive.
Pro Tip: Ensure the pedal set you buy is made specifically for your vehicle model. A universal-fit set may not be secure, which can be a serious safety hazard.
Your Car, Your Canvas
Your pre-owned EV is a fantastic platform—a blank canvas waiting for your personal touch. With just a few weekends and a modest budget, you can transform it from a vehicle that's simply "new-to-you" into a car that is truly, uniquely yours. These 13 upgrades are more than just accessories; they are smart investments in your car's longevity, functionality, and your daily driving enjoyment.
Don't be afraid to get your hands dirty. The satisfaction of installing an upgrade yourself is a reward in itself. Pick one or two projects from this list to start, and you'll be amazed at how much you can enhance your electric ride.
