I have to say there are some cars here that would probably never be seen at all, whether they were done from scratch or otherwise. The fact that we have them to use and someone put some work in to get them here should at least be appreciated.
I do see others viewpoints, but when it come right down, its still your choice If you want to use them or not. I have to say I've had a blast as well with Bazza's mods, especially the 1967 F1 cars.
I haven't had a chance to use them much, but the 2002 was really fun to drive, although I must admit I'm partial to the round tail light earlier version, I think it was 1968-1973.
