Thanks everyone! I've already found tons of great info! Appreciate it.
One noobie question... I haven't been able to find any online part websites here in Japan. There are tons in the US though (I have a US credit card with a US address).. Unfortunately, it seems there aren't many options for 318 parts on US sites. I've only found stuff for the 325i... Are parts for the 318 and 325 interchangeable (not talking engine or transmission of course), specifically bushings and coolant systems?
