Bit of a hard one really mate.

The trouble is that bad body work really puts people off, if its got tax and MOT and its not got stupid miles, probably 2500-2800. If the body work is really shabby with no MOT and loads of miles probably nearer the 1800 mark.

Below average but drivable 1200-1500
Average cars 2000
Really clean ones go for 3-3500.
Exceptional cars seem to be going for 4500-5500

This is just based on sold prices from piston heads and ebay over the last year or so. I have seen cars go for as little as £500 and for as much as £6000.

Keep it and sort the body, it will only appreciate.
