Leasing a car is a great solution if you want the benefits of a new ride without the commitment of buying it immediately. But if you're itching to make some modifications and personalize your wheels, be careful with what you want to change.


While lease agreements typically prohibit permanent alterations like tinting windows or lowering your suspension, not all hope is lost for wannabe modifiers. Many leasing companies will grant permission for minor mods like seat covers, floor mats, or roof racks that can be removed later without damage. The key things to remember are thoroughly reviewing your lease terms upfront and getting written approval from the leasing company before making any changes. With some careful planning and communication, you can likely make acceptable modifications to put your personal stamp on your leased car. Just don't go drilling holes in the bumper or painting racing stripes down the hood without checking in first. 


There's a better way to drive with a FINN car subscription. Enjoy all the perks of having a car without the usual hassles. With FINN, you get hassle-free insurance, maintenance, 24/7 roadside assistance, registration and titling all taken care of. Driving should be easy and with FINN, it is. 

What modifications are allowed on a leased car?

You may be wondering what customizations and modifications you can make during your lease term. While major modifications are restricted, you do have some options to put your personal touch on a leased car.

Interior accessories 

Most leasing companies allow you to customize the interior with items like seat covers, floor mats, and steering wheel covers that don't cause permanent changes. Dash cams and phone holders are also usually approved.

Exterior accessories

Adding exterior accessories like roof racks, bumper guards, hood deflectors, and rear spoilers is generally allowed as long as you don't make any permanent alterations to the vehicle.

Can you put subs in a leased car?

Typically yes - with the right gear and approach. Non-destructive amps and subs that plug into your car's power outlet are lease-friendly, allowing you to enhance the bass without hacking up wiring. Just avoid permanent mods that require drilling or rewiring unless explicitly approved. And take care not to blast the volume so high it vibrates and wears the interior over time. With removable upgrades installed properly, you can feel those beats pulsing without shaking up your lease. 

What modifications are not allowed on a leased car?

When you're leasing, you want to avoid making permanent modifications that could lower the vehicle's value or violate your lease agreement. 

What happens if you tune a leased car?

Tuning or modifying the engine of your leased car may offer tempting performance gains, but it's a risky move that can end up costing you big time. Lease agreements strictly prohibit engine tuning, and doing it anyways can lead to serious financial consequences and headaches when you return the car. The leasing company may hit you with fees to undo the changes or charge for overall diminished value. They can even terminate your lease early and demand immediate repayment of the remaining balance. 


Plus, you'll likely get stuck footing the bill for any engine damage or reduced reliability caused by the unauthorized tuning. Excess wear penalties for added mileage or decreased fuel economy are also a possibility. And contract violations on your record could hurt future lease or finance applications. While the power boost sounds nice, it's way smarter to keep that leased engine stock unless actually own the car. The punishment is nowhere near worth the short thrill of tuning a vehicle that isn't really yours.

Can you modify the suspension on a leased car?

Lease contracts prohibit suspension alterations that could impact handling, reduce value, or lead to costly repairs down the road. Dropping your leased vehicle can prematurely wear components like shocks and struts, plus lead to ride height violations. And when the lease ends, you may get slammed with fees to return the suspension back to stock settings. It’s not worth it. For a peace of mind lease experience, keep that suspension factory fresh until you actually own the wheels. Suspension dreams will have to wait. 

Altering the exterior appearance 

Custom paint jobs, vinyl wraps, racing stripes, and other cosmetic enhancements are generally not permitted without approval. Tinting windows darker than legally allowed is also prohibited. Light tints may be approved by some leasing companies.

Cutting/Drilling

You can't cut, drill, or weld any parts of the vehicle frame or body panels. Adding accessories like brush guards requires bolt-on installation with no permanent alterations.

What happens if you modify your leased car?

If you want to modify your leased vehicle, this will require some careful consideration. While you don't technically own the car, minor modifications are sometimes permitted if done properly. 


Here are seven key tips to keep in mind:


  1. Thoroughly review your lease agreement first. Many prohibit permanent modifications like tinting windows or altering ride height. But some allow reversible accessories or bolt-on parts.
  2. Get written approval from the leasing company before making any changes no matter how minor. Unauthorized mods can lead to fees or lease termination
  3. Focus on removable accessories like floor mats, seat covers, phone mounts, or roof racks that don't alter the car permanently.
  4. Save any parts you remove to reinstall later. Returning the car in an unmodified state is key.
  5. Avoid any performance modifications whatsoever. Tuning, turbochargers, etc. are strictly prohibited.
  6. Watch for wear and tear damage caused by accessories and remove them if needed.
  7. Expect to pay for any repairs or diminished value from unauthorized modifications.


With proper planning and approval, modest customization of your leased vehicle is possible. But drastic mods come with serious risks, so know your lease terms and tread carefully.

What to do if you already modified your car

So you customized your leased car without fully understanding the implications. It happens. Here are some tips on navigating this situation:

  • Review your lease agreement – Re-read the fine print to understand what's allowed and prohibited. This will guide your next steps.
  • Assess the modifications made – Determine if they are reversible or permanent. Reversible is better. 
  • Contact the leasing company – Explain what you did and ask how to address it properly. They might help you out with this. 
  • Reverse unauthorized mods – If required, safely remove or undo customizations to restore the car's original state. Keep all the parts.
  • Pay any assessed fees – There may be charges for repairs, diminished value, or violation of lease terms.


With patience and persistence, an honest mistake can be remedied. Don't compound it by ignoring the issue. Work positively with the leasing company to get your car back to lease-compliant condition.

Can you modify a financed car?

Generally, you have more freedom to modify a financed car compared to a leased one since you own the vehicle. But there are still risks to be aware of if you customize a financed car:


  • Modifications can potentially void portions of your finance agreement or insurance policy if not done properly. Always review your loan terms first.
  • Certain changes like engine tuning may require informing your lender, or they may need to approve co-signing any additional loans for parts. 
  • Customizing can affect the car's resale value down the road, for better or worse. Keep mods tasteful if you plan to sell.
  • Adding performance parts or altering critical systems can impact reliability and warranty coverage if not done right.


While financing does provide more flexibility, modifications still require research and care. Ultimately, full ownership of a purchased vehicle opens the most doors for customization with the least restrictions. But buying a car has its own pitfalls - steep depreciation, maintenance and repairs, insurance haggles, and DMV hassles to name a few. Leasing, financing or buying all come with compromises. 


However, there is another way. A car subscription from FINN offers the best combination of access to vehicles with flexibility to swap rides and avoid total commitment. Get hassle-free insurance, maintenance, 24/7 roadside assistance, registration and titling, with just one monthly fee. 

Final thoughts

At the end of the day, modifying any car you don't fully own requires walking a tightrope. Leased rides especially limit what enhancements you can make without permission. And even financed wheels come with risks if you don't mod responsibly. Therefore, always review your agreement and get approval before making any changes. A few exterior accessories here and there are probably fine, but drastic modifications can land you in hot water. If you already took the plunge on customizing your lease, work with them to fix it.


For maximum driving freedom with minimum fuss, choose a car subscription from FINN to get the best car lease deals. A car subscription with FINN gets you access to all the perks of having a car without the usual hassles. Insurance, maintenance, 24/7 roadside assistance and more - all handled for you in one simple monthly fee. No tangled mess of bills and paperwork. No playing mechanic in your garage. Just grab the keys and go for a carefree drive. A car should fit your life seamlessly, not weigh you down. And with FINN, now it can.
