A great car I bought used with 65000 on it. Have just replaced struts, plugs, belts, O2 sensors (rear), front stbilizer links. Average 27 - 28 MPG on premium @ steady 68 MPH. Paid 13K, just put $1600 in for above repairs. Excellent road car. Fussy about tire pressures on Potenzas G009. Too much results in hard ride. Bose great, A/C fantastic, not much wind/road noise. This is not a cheap car to maintain at the dealer, however I highly recommend using only the dealership for service. OEM replacement parts for this car are the only way to go. It should be put on the computer every time it goes for service. Car should go 200K miles relatively trouble free
Bose, leather, transmission. Absolutely no vibration from this car at idle. You shouldn't be able to tell that it's even running. I've got almost 105K on mine and it's very smooth.
Better seat motors. These are a little glitchy. Independent rear suspension would have made these cars real burners and would make the M even a better car.
