my 06 STi is sitting at 15k on KBB, I put the chassis miles (141k), but i have no rust and ive replaced almost everything at some point in the 9 years ive owned it. the trans is the only thing i havent rebuilt/replaced (i'm sure i will eventually, but it's running great so not really needed at this point). granted, i wouldnt sell it for any less than 50k (aka i'm not selling it lol).
Absolutely. All GDs are 04-07 - and I am not a collector, but I'd have built a second GD in newer shape than my 05 ( which isn't in bad shape even with 260K+ miles) rather than buy a new-one, but I couldn't justify the cost of a GD in nice shape.
Anyway good ones are getting scarce . . . a vastly better term than rare
