I guess it all depends on a number of factors most notably the condition of the car, the colour of the car, the mileage, how many owners the car has had and how desirable the particular model is.
If she has been off the road since 93 then will she require some re-commisioning to get her on the road again? Brakes can seize, brake fluid can go bad, fuel can go bad.. engines can deteirorate if just left sitting.
To give you a rough idea of the market, a 1 owner 5 door 16Valver, in very good condition, went for £2400 on ebay last week. It had 93,000 miles and was a J plate, since 8Valvers usually go for less then a 16Valver I'd guess yours would sell around the same due to the lower mileage.
The buck however always ends at how much someone is prepared to pay.
The more you get the better for us as it means the values are going up.
