The Volkswagen Kombi van reached iconic status, with even a school lunch box fashioned in its image. During those early years, the Volkswagen Microbus morphed into various forms.

Classic Car Overview

Here is a rare opportunity to purchase a very well sorted track car that is an absolute monster on the race track, yet extremely reliable. The car has been extensively upgraded using only the best parts available without concern for the costs incurred. A Pro Charger D-1SC supercharger as well as many other engine modifications have been added producing approximately 600 gross horsepower and over 500 horsepower at the rear wheels in a car that has been weight reduced to just 3,000 pounds. The resultant acceleration and top speed are awesome. But it’s not just the engine that has been upgraded; significant modifications without regard to cost have been made to the body, chassis, suspension, steering, brakes, electrical interior, wheels and tires. The end result is an extremely fast, safe and reliable track car capable of extremely low lap times capped off with a state of the art data gathering system to help you analyze your every movement on the track. This car is located in Troy, MI and can be purchased complete for $49,928. Two binders detailing the upgrades and including receipts are included. Also, a video of the car at speed at Waterford hills Raceway is available upon request. May consider an interesting trade. . Contact Michael@sellyoursportscar.net or call 1-248-227-8604
