hey just wondering how reliable are the E36 M3s?? or the S52 block?? i just can't seem to find anything that i would feel comfortable buying and i'm gonna need a little more of a confidence boost buying a car of this age with this many miles. i'm really into them i'm just nervous about the mechanical issues and the cost of the repairs all that good stuff. can anyone tell me what to look for in buying one and help me out here?? maybe some common problems?? and basically....anything under the category of reliability or risks or value or just anything i need to know that will make me feel better about purchasing something i love so dearly. thnx!!
