When I was 11 or so, I ended up with a Revell '57 BelAir kit. I had only been gluing stuff together for 3 years, so the multiple features boggled my mind! At some point, it turned into a guided missile, as it went flying down the hallway from the dining table, up against my sister's bedroom door! I gathered up the pieces, crammed them in the box, and never finished it. It's the only time I ever tossed one. I have never built a '57 Chevy to this day, and I have several in the stash, both AMT and Revell.
I have had some rough times with those multi-piece body kits from several of the companies, even Palmer!
