I found a 89 Greenwood Vette at a used car dealership for $6900 the car is clean and has the dash emblem with the Greenwood Motorsports serial # looks to be a nice car and runs good. It also has a box of documents from Greenwood but I really did not look through it. Other than a full body kit, wing, and 3 piece wheels was the engine upgraded? I know its not stock from what I can see like headers, intake hose, injectors, and so on but it also has a cam due to the way it idles. It pulls pretty strong when I took it out for a test drive. The dealership does not have any history on the car so I dont know what the other mods are and who did it. it looks well kept for a 71k mile car with original paint. any ideas?
