I've been in the process of rebuilding a foxbody Mustang and have had a full resto done on the body. Part of my issue is my own fault, I did not get a written estimate on the work. As a result, the final bill was significantly higher than the original estimate. I should have known better. Anyway, before bringing the car to the shop, I, with the help of a friend, disassebled the interior, pulled the engine, tranny, etc., then brought it to the shop for the body work and paint. I get a call from the shop to pick the car up so I can install my parts. The owner of the shop notifies me that the car still needs to be wetsanded, but he wanted me to finish my end in case we caused any scratches or chips. Upon reassembling the car, we found issues with some of the body shop work: rear wing not installed properly, original color showing on the inside of the side skirts, a good scratch in the side, etc. I paid the shop about 3/4 of the bill, with the balance to be paid when the shop completed the work. Well, I spoke to the shop owner and let him know that there were some issues that needed to be addressed, and suddenly he gives me flack for not paying him in full and he usually doesn't let a car leave without full payment. Now I'm getting nervous about bringing the car back, in case he doesn't make good on fixing these issues and not releasing my car until I pay. What kind of rights do I have here? I already overpaid for the job, and the shop owner did a real 180 on me attitude-wise, so I have questions. Sorry for the long exposistion.
