Few questions
i'am right in thinking all 525i's are m30's ? and non came with a 2.5 m20
what they like in terms or rust, better or worse than an e30?
also where do they rust as they are bound too? same as an e30? are inner arches as bad as e30's? are the sunroof trays bad, do they have jacking pads in the footwells that rot like e30s
Any particular problems that affect these?
