Get a garage to look at it for you and ask them to tell you exactally whats wrong with it and what needs doing, Then before you sign to anything post exactally what they said up here and give it 48 hours, By then we should of all been able to come up with ways to get it sorted or parts we can get hold off, The advantage of Mk1s and Mk2s are that theres always a few at a scrap Yard, So replacing old wings and bumpers is always easy. Also, If you need any hard to find parts E-bay is the place to find them, Not always cheap mind, But they always have what you want there.
