2013 X1 35i xdrive M-sport - 75,000 mi.
-Bought CPO with 19k mi.
-New Tires Conti Xtreme Contact - 45k
-New Front Differential (covered - dealer near seen before) - 45k
-New Water Pump (covered) - 50k
-New Front Brakes (covered) - 50k
-New Rear Brakes (self) - 70k
-New Rear Diff Seal (covered) - 73k
Pretty much just oil and filters every 10k. CPO warranty has been a godsend given the Front Diff and Water Pump failures...It comes off this December
Otherwise, amazing car, would only look for a newer 3-series given the chance.
