I'm going on 4 years in January since I got my EVO, i never did any performance mod on the car, she is still 100% performance stock with only 19xxx miles, also I'm the original owner.

should I keep her that way?
or should I do the basic bolt on mods?

I figured this car is an investment and would hold the value better if it always stays engine stock.

what would you guys do.

please try to understand what I'm trying to do before you respond with a dumb answer

 

Personnaly if i was buying a seconf hand car I would like it bone stock like your if possible, although a few bolt on basics such as filter, exhaust, and a tune would do wonders for your car, you would love the difference and all without losing the stock feel / look, and if required, it could always be put back to bone stock very easily. If I was in your seat I would do the stuff I mentioned above and store the stock parts properly for the future if you need them.

 

Are you planning on selling the EVO any time soon. If your content with your car and plan on keeping it for a couple years I would do basic bolt-ons nothing permanent. This way you will be more happy with your car and you can always take off your mods if you plan to sell.
