How much do you intend to spend on restoring it? If it's £2000 to begin with and you spend another £2000 on it, don't expect it to get £4000 for it when you come to sell it.
Mine is a previous owner, full service history, never modified car. I've had quite a lot of work done in the 5 years that I've had it and still have some more planned. When it is finished, hopefully to concourse standard, I will be over £10,000 into it. It won't be worth anywhere near that if I wanted to sell it, but where could I go and buy a similar car from? Restoring a Mk2 is something that you do because you want to, not because you want to make some money.
