very nice car OP. when it comes down to it, people are going to shell out more cash for a rust free, great condition M3 because it is just that... rust free and in great shape.
well maintained 15 year old cars are very hard to come across nowadays. once they start to build rust a ton of other problems come with them. a 320,000km M3 may be clean, but bring it to a reputable shop for a diagnostic, and I can guarantee they'll find AT LEAST a couple thousand dollars worth of maintenance required.
