1966 Jaguar XKE (E-type) Coupe. I'm willing to argue, enthusiastically, that the E-type is best car ever made. It's, at the least, the most beautiful. Built (at first) with a simple 6-cylinder, it was one of the fastest production cars of its time but also had the comfort and practicality of a GT, for a third of the price of an equivalent Ferrari. It's near the top of my dream-car list.
