I think it hasn't sold because it's not as original as it should be - I was advised not to buy it (see posts) by TMers who know a lot more about these cars than I do.
I loved the colour - but it's none standard.
This car has had three £10k price rises - the owner seems to be more interested in getting a top price then selling it.
Its not over priced for a Turbo, so buyers are being put off for some reason, and the seller declines to lower the price to move it on.
Pre 90 prices vary a lot depending on condition, mileage and model - I am seeing quite a few POA's - presume this means dealers dont want to price it too cheaply in a rising market.
You know it makes sense!
