I'm in the same boat, basically inexpensive car models, even though many are 60 years old, usually 40% off at HL and virtually no AM for any of them. Building, as I do, mostly curbside, my overall outlay is peanuts compared to my aviation and armor related modelling hobby. I'm working on a 1:32 Bf 109G-14/AS right now, and between the kit cost and all of the AM I'm dumping into it, will end up being well over $150 before I'm through, vs the average cost of $20 or so per car model. I have no complaints.
