It would depend on what decade I built it. My detailed Bill Elliott Bud 11 car took two kits, aftermarket paint, decals, and various photo-etch bits and accessories. I built it in 1993 and it cost probably less than $70. Kits were cheap at Walmart, maybe $5 or 7 each. I think the decals were maybe $5, Tru-Match paint was less than $5, each one of those bags of Detail Master sets were less than $5. Each decade the price of kits went up a little, but right after 2010, wow! Double! and every year it seems a few dollars, not cents more. I'd say to try and build the same type of detailed car today (not NASCAR, because you can't give the '90s models away), I might have to spend twice as much, depending where the model was purchased from.
