A friend of mine used to have an AWD Galant that had the 3000GT motor in it. It was not a custom job either, it was an optional package for the Galant for a limited production run or something. Now THAT thing was quick...and quick to break halfshafts all the time lol.
My GMC Typhoon is a sleeper unless you know it...most people just think it's a Jimmy with a bodykit. I love sleeper cars/bikes.
