Steam Crazy - I agree that there ae some great cars out there that don't necessarily cost a lot and have lots of detail like opening doors, hood, antennas, etc. - you just have to spend some time tracking them down. I try to model the '50's to '60's so virtually all of my models are pre-1970. Here's another 'Vette.
Haawke58 - I can't explain either why the cost of 1:43 cars jumps by factors as compared to 1:64 scale. I probably have 50 cars on my layout and I'd say 90% cost less than $10 and none over $20, so they are out there.
