American Graffiti is one of those movies that most people can relate to. The burger joints, the cruising, the stop-light drag racing was all accurately portrayed in that movie. The F&F franchise is so far fetched you can't relate to it but unfortunately you have all these young kids out there trying to emulate the movie and crashing all over the place. And that is why I have such a dislike for those movies.
I would also add '81-92 Dodge Ram pickups and Ramcharger to that list, that body style has never been done in plastic. I would do 2x4, 4x4, short bed, long bed and maybe even a club cab and dually. I would include lots of accessories for the 4x4 kits too.
I keep a log book for my nascar builds, I find it helps to keep track of what I need for donor kits. I keep them categorized according to make and year group(i.e. '95-99 chevy). I write down the year, car#, sponsor and then i have columns that I check off when i have the donor kit i need. And then when the build is done i highlight the entry in yellow so that way i know not to count that one anymore. As for my street cars and trucks i don't keep any records of any sort, its a hobby for me so therefore its irrelevant to me as to how much i paid for it, how long it took to complete it and so on.
