My parents have owned an Escort Cosworth Monte Carlo (No. 68) from new, and are looking to sell as they're approaching retirement and need something practical for a new dog. They're struggling to decide on an asking price and have asked me for advice.

It's got about 75k on it, full service history, shows as 2 owners (my dad's old company and then my mum - both at their home address). It's never been crashed or modified in any way. The gearbox crunches at high revs from second to third but other than that it's mechanically sound. Cosmetically it's in need of a little TLC to get it mint again. There is a rust spot by the fuel cap and some minor dings and scrapes around the paintwork. The alloys are all fairly corroded and need a refurb or replacement.

Does anyone have an idea where to price it? I've got no clue as to what the market for these old beasts is doing and would appreciate any pointers.
