I have an X5 with 254,000 miles and counting. Mine cost over $18,000 so
far in repairs with most of the labor done for free under trees! (shade tree mechanics).

The parts prices are pretty steep.....$200 for window regulators (needed 5), fuel pump was $405 (plus $200 to put it in), PCV (Oil Seperator) went bad twice, only $150 but hours to get it in and out, Oil canister gasket $5 (but you have to take 1/2 the motor apart to get to it), transfer case $900 (refurb, would have been $2200 OEM part, plus $300 labor), ABS brake module $300 (refurb service out of Idaho, would have been $1200 OEM), etc.

I would say your mileage is just about where all the $#$# starts! Of course you have to do brakes, rotors, hoses, bulbs, water pumps, bearings, etc. like any other car.

Even though mine is running the motor mounts are shot and its $1500 to replace 3 that are needed.

BTW I never had a transmission issue (don't change the fluid ever) and the core motor is bullet proof......just that lots of stuff breaks way sooner than I think it should have on a $47,000 car.

I'm going back to Japanese........
