My taste in Corvettes have changed over the years. I never was a fan of the C1 or C2. And I don't get gaa-gaa about '63 split rear window coupes. Zora Arkus-Duntov was against that design from the outset. He said it was a detriment because it restricted rear view for racing purposes. He struck a blow for functionality over styling when the split window went away for '64.
When I was a kid, the C3 was current production, and I thought that was the coolest car going. But by the time its run ended in 1982, I was down to calling them "Coke-bottles", and their performance was really pathetic with 205 TBI injected HP from the 350, and handling that was unkindly described as "like a pogo stick". The C4 was a big step forward in handling when it came out and over its time, outran a lot of more expensive sports cars, especially when it got the LT1 in 1992. I have a 1985 because it was the first year with the TPI engine, and the last before it got ABS. I had a thing back then about driver nannies, and wanted to make sure that I was responsible for whatever the car was doing. But over the years, I've come to look at the C4 styling as too muted, and it fades into the background in any gathering of Corvettes.
Then GM came out with the C5, and the first appearance of the LS-series engines. The C5 Z06 is probably the best bargain in track day cars going. They can be bought cheap and fitted with built LS3 engines making 550+HP, and nobody in a N/A C6 or C7 will embarrass you. But I've never been a fan of the big-butt notchback styling...
The C6 is my current favorite for body style. Very crisp and nicely proportioned. If I were to buy another Corvette, it would be a C6 Grand Sport.
The C7 is nice, but a little too swoopy for my tastes.
