I want to tell my 1970 VW fastback. I am not sure how much to sell it for so I need some suggestions for that. It has a Type 3 engine. It is carborated. The engine was completely rebuilt a year ago. It has a new exhaust. It needs new paint and upholstery work. It runs pretty well. It doesn't have a radio. How much do you think I should sell it for? I know the fastbacks are not very easy to find anymore.
