My advice; don't buy a kit of parts. You will spend the next 3 to 5 years trying to assemble unmatching bits without the proper info. After advice from your local A7 club get a complete car, in any condition, which you can just about afford on your budget. Don't take it to bits but get it running. Worry about cosmetics and originality only after using it. Best of luck!
Thanks for this Terry, it may be that I have to save up some money to buy a more complete car. I am still on the hunt anyway!
