'67 / '68 Camaro. I appreciate the Muscle Car era, because it feels like blunt honesty to me, and the "keep it simple, stupid" philosophy. "Hmm. Need to go faster. Need more engine." Though there's many "dream cars" of the muscle car era (some very noteworthy ones already mentioned!) the '67 / '68 strike me as being very attainable, and the lines on the car are, imo, gorgeous. I like the flowing curves of the '67 / '68; I don't much care for the straight lines on the '69.
First gen Audi TT Quattro coupe. Love at first sight. From a design aesthetic, I think it's visual poetry; the themes of the Audi rings are subtly repeated throughout the design. Simple, clean aesthetic, with form following function.
C3 Corvette, and specifically, the '80 - '82 body style. This was the first car as a kid that caught my attention; the first car to really capture my imagination.
