I am interested in restoring a 1967 Mustang. The body is in excellent condition, no rust, the interior needs re upolstering, new carpet and minor cosmetic things on the inside the engine needs tunning and probably some parts of it could be replaced. The last time it drove was 5 years ago but its been sitting in the back yard at a friends house since. My question is, is it worth restoring and how much on a guesstimate would it cost to get it to good running condition? I figured Id get it to good running condition then over the years slowly get it to show car quality.
