Sorry, was bored and had to point this out....
"Luckily there is an easy way to see what you are getting into. GET THE SERVICE RECORDS!
I strongly advise buying an E30 without the service records.
If the owner did not take the time to document the work done to the car chances are he wouldn't take the time to make sure the work was done properly. There is also the possibility the owner had the car serviced at an auto repair "chain," or "mom and pop" mechanic."\
