I recently inherited a 1986 735i with less than 100k on it. The car was used in the midwest and is in great shape both mechanical and body wise. I have read some of the postings and I can see that I do have a HVAC problem as discussed here, and probably a problem with the fuel system. I have not been able to locate a service manual of any substance from Haynes or Chilton to cover the seven series. Any suggestions on locating a manual or written reference material which will help me troubleshoot this vehicle will be greatly appreciated. I have to concur with many of you that this is a pretty impressive vehicle and I would like to hold on to it for sometime. T.I.A.
