The '55 to '57 Chevy and the late 60's Mustangs are in a few top tens here. I too really enjoyed building the '57 Chevy, and like the '62 Electra, I bought another. I haven't tried the newer moulding yet though. The Revell '69 Mustang Boss was also a delight to build and they looks so good. I tend to go for older tooling kits for their simplicity but so far of the modern tooling kits I've done, the Mustang, for me, has been the most enjoyable, but as Chris said...
