I lean towards vw/audi etc family of kits but dont limit myself to just those and probably have more others than vw. I Have bought kits based on the box art or just to see what they are like. n example of this would be the amt original customising 57 chevy and 50 ford kits I really only got for the boxes. The chevy was a wreck but the ford turned out to be mint. As far as manufacturers I buy from any that have something that I like the look off but I prefer the japanese brands or newer revell for subject matter that holds my interest or if something is a screaming deal I'll take a chance on it. My favourite parts of building is doing heavy custom body work to suit my tastes and my least favourite part is final assembly/completion as I find it a bit depressing until I start the next one. I dont mind a curbside kit but prefer them to have an engine and decent interior but chassis detail isn't important to me as how many people ever look at the models chassis once completed (hot rods are an exception to this as so much of the look depends on the chassis). I like glue kits but also use glue on snap kits and the more options the better for me and would like to see some of the muscle kits come with modern engine options and alternate parts for lowering. As for a non subject matter suggestion revell in europe need to use decent boxes, once they have been opened once they lose all rigidity and are just useless for anything else, and I would refer them to the us boxes that manage to hold their shape for long after the kit is built.
