Best. Mod. Ever. ???

[TypeA]

Performance, installed a double din with dvd playback in motion, nav and backup camera. While it seems like a convience it really was a drastic perfomance and feature upgrade over the stock deck.

Aesthetic is kinda a toss up. Replacing the stock grey 17" turbo twist rims with 19" SSR GT3 rims was drastic but then Eibach lowering springs (even just the modest 1" drop) really changed the look from inside and outside of the car, far more than I thought it would.

Convience is easy, there is nothing cooler than rolling up to a light and raising the top without worrying the light will turn before its fully up. The best convience mod didnt cost me a dime and is used daily, top up\down in motion hack.
