No more dreamers than half the supra owners currently trying to sell theirs at extortionate prices. I dont think I've actually seen one car priced at £20k sell, let alone some who can't get theirs sold for sub £12k. The category of ancient cars definitely includes Supras with the majority pushing 20 years old now and most are on 20 year old components. Its only a small minority have refurbed the suspension/chassis components and engine (all of which, low mileage or not, need a refresh at that age) which would justify any sort of enhanced price
The whole 90's car market at the moment seems to be entirely false. Saw someone looking £15k for an S15 the other day too and the odd punter looking £7k for an NA auto with a load of commentors saying "great price/ hows this still here/ bargain for a clean car".
No wonder the market seems to have stalled, its become totally ridiculous.
