I have a 1973 240z that I pulled out of a barn 2 years ago. I have no time to work on it anymore. Does anybody know of a good mechanic who is good with these cars in the Metro Detroit MI area. I live in Westland but will consider all help. the dealers have oil changers. It seems diagnostic techs are far and few between. After a head job I have no power, black smoke, and poor runability, the car is basically unusable. Thanks, Dave
