I just became a beta tester for "MyCarFax" so I was able to find out some more information on service history.
Besides the recent service last month to replace spark plugs, oil, diff fluid, and software update I found that in May of last year (at 22950 miles) the following was performed by BMW NW in Tacoma:
Maintenance inspection completed
Recommended maintenance performed
Brake fluid flushed/changed
Oil and filter changed
Cabin air filter replaced
Front wiper blades/refills replaced
Air filter replaced
My E92 order has been submitted so I'd like to time this sale to coincide with the new vehicle delivery, if at all possible...
