11: 1993 Dodge Viper
The original Viper was a groundbreaking halo car pioneered by Bob Lutz. He enjoys driving more than anything else, and thus was a pioneer in designing enthusiast cars. Leno has owned his 1993 Viper since it was brand new. He washes it once a year and has kept very low mileage (via Car and Driver).
The 1993 Viper is about as barebones of a sports car as you can get. There is no air conditioning, no ABS, and no onboard computer. The original 1993 Dodge Viper is a street-legal race car with a 400 HP V10 engine. With a high price tag at the time, the Viper wasn’t a cheap toy to buy either.
