I bought my '95 525i 5-sp 26-months ago. I've put over 40,000 miles on it in that time. I've changed rear shock mounts which cost about $30 plus some $20 spring compressors I can always exchange for a full refund. Other than that I've only changed the oil and replaced the crappy Avon tires it came with with 234/45x17" Yokohama W4s for a total including mounting and balancing of $500. I replaced wiper inserts once but I went to the dealership on a Saturday to get them and the parts manager gave them to me since they were technically closed for the day. I can't think of anything else I've had to do . . . oh yeah, the pollen filter for about $16, and air filter, and one low-beam bulb (the illegal kind) for about $20. I guess that makes my total, including buying the car and new tires, somewhere around $6100 USD after 40,000 miles of use.
