I think the value of Mk3 is on the tumble - now the Mk5 is out, it looks pretty old fashioned. It hasn't got the cred of the Mk2 either, so my guess is they'll be getting very cheap over the next year / 18 months.
I'm thinking of selling my 1998 Mk3 GTi, but I reckon I'll be lucky to scrape ?3k for it.
Hey ho, such is life!!
