When I was 18 I gave up models because it was looked at as kid stuff. That was in the 80's. I gave away what few I had built. I started back building in 89 or 90 and decided I did not care what friends and family thought. So glad I got back into it...
I was very disappointed with AMT/MPC Twister Vega, and the 74 Road Runner. I made a nice model out of the 74 Road Runner but the Twister Vega really disappointed me I gave it away.
