I have been offered a 1991 H reg 2 Door TDI Discovery with belive it or not only 19'500 miles genuine miles, I know the miles are correct as it is a vehicle I have known from when it was new, it has the full service history (up untill 3 years ago all the stamps were the main dealer where the owner bought it new from). The body is unmarked apart from some paint has flaked under the wheel rims and there is some chips on the edge of the drivers door where it has touched the garage when opened, there is also a dent in the rear bumper. The old guy selling this has not named a price and wants an offer, the thing is I have not got a clue what it is worth and I do want to buy for a fair price. So opinions needed on what this gem is worth!!
