All of them. I've replaced my skills with the hammer with those of the monkeywrench. There is no vehicle known to man or god I can't trick out.
Side note - I see your check engine light is on. You may need a tune-up. Bring it on by the garage @13thFloor and we'll see about a valve and soul lube job.
Ahh, so something like this is more your speed (don't like to mod the bodies on those babies, handling is perfect as-is). Incredible cars to drive, but finding the right engine parts can be an adventure unto itself.
