I'm a tuner enthusiast as well as an autocross racer. Bought the car at 175k miles and its not given me any problems. Its N/A but with a few mods I've bumped the HP up a good 40 to 50 over stock. A lot of fun to drive, great to race. Working in the engine compartment is no fun at all though. Not much room. Still no leaks in the t-tops, everything is functional. Happy owner.
Mid-eng rwd is a blast. Solid platform, both N/A and turbo have a lot of room for tuning
Snap oversteer is vicious, I'd suggest wider tires, stiffer springs and a set of good swaybars. Helps counter this a lot + improves all around traction incredibly.
