I have been a Volvo owner for quite a while. I am considering buying a 89 BMW 735iL. It has 157,000 miles but the mechanic who owned it rebuilt the top end at 149,000 because it had a head gasket leak and it was convenient. It appears to be well maintained and drives like a dream compared to my Volvo 240. All the electronic bells and whistles scare me a little. I've also read a few posts on the internet where people have experienced driveshaft vibration problems. There also seems to be AC and blower motor problems with some of the late 80's models. Those things really scare me due to expense. Can anyone give me an idea of the overall reliability of the 735i sereies vehicles and personal opinions? Do these cars have undercarriage rust problems? Also, since I since these cars are new to me (I don't think I've ever ridden in a BMW much less driven one) what do the E23, E32 and E38 mean? The guy is asking $7,800. It seems like a fair price. I tend to buy a car and drive it till it dies. I'd be grateful for any input.
