Or... expand the horizon to a "former" race car like a Huffaker built one... If there's enough paperwork available to get it tagged on the street again, boy howdy would this be fun....
Buy new Huffaker Midget SCCA HP/FP Road Race Car, MG Midget, Spridget, Sprite in Rogersville, Missouri, United States, for US $42,500.00
I actually know who bought this car. It's still a race car that he's set SCCA records in against modern cars.
