The owner of this car is a friend of one of the crew members at TW.  I spotted the car in the parking lot and had to check it out.  I figured a '81 Buick would be boring and run of the mill, but from the smirk on the owners face I knew that it had something special under the hood.  This would be a good car to call a "sleeper".  I had no idea and I bet most people don't either.  A touch of the throttle, spool of the turbo and all you would see would be taillights!
