I don't have the money to race Ferraris, but you don't see me going out and buying a crappy Mondial with 90k miles and racing at my local track. Sometimes you're just making yourself look ridiculous.
If you cannot do something right, don't do it at all.
Last time i tracked my 88 CRX with 200,000kms on it i was embarrassing cars costing 10 times more. Granted if my local track was bigger and had more straits and less turns i would have got murdered. I have a fully modded suspension but as of right now still running the original tired stock 1.6L. Only have a exhaust as far as engine mods go. Not much could keep up with me in the corners, the G35's/WRX's were keeping up but nothing in the high HP RWD big american car types had a chance. I was pissing off ALOT of mustang drivers.
My car looks stock though, no spoilers, no body kits, hell its rusting apart but i intend to do a full body restoration as soon as i swap in a new engine and trans.
