+1.

Out of my three bmws i must say, the X has had the best heatlh of them all!

97' 540i - Cooling system but at 120k the suspension is gona go soon, seats starting to fail
95' 740i - 148k Tranny, Cooling, exploding fan, same thing with the suspension
01' 4.4i X5- I dont know how much a CPO car should hold up to, but just at the 100k mark things didn't really die, very small things. O2 censors and a cooling overhaul are about it

Now at 120k im amazed at how the tranny is still pushing like day 1, other than that, i love this car for its durability so far..

150,000 miles.
 

I heard many years ago european and japanese cars are design to have a 200,000 km service life or 150,000 miles. American cars are design to have a 100,000 miles service life. And Mercedes are design to have a infinate service life (I don't want to start anything but that is what I was told from reliable sources).


But that is my .02

I have an '04 3.0 auto with 109k miles and everything is in tip top shape- the only problem i have fallen victim to is the dodgey a/c, cold on the left and hot on the right :banghead:

but car still runs like new and i look forward to driving it day in and day out :D

77k on mine, quickly escalating. Rebuilt front (and currently rear) suspensions. Other than that, it's been routine maintenance. See no issues getting another 125k out of her. That is my goal - 200k on it... and by then I'll be ready for something new.

I would expect that the sales person was giving you the average life expectancy, and 100k miles is probably on the low side. Statistically he is correct, but as with all statistics there are aberrations. Some will never have a problem for 250k miles, whilst others will get unexpected (and premature) failures - hopefully most will be minor (if expensive) and easily fixed. Almost all of the problems I had under warranty were minor but annoying electrical/electronic (mirror motors, locks, A/C fans, pano-roof, starter motor). Until the gearbox failure, the worst mechanical failure was the power steering hoses leaking.

When I bought my 'X', I expected that as the powerplant is diesel it would last 250k miles along woth most of the primary transmission components (unfortunately the gearbox crapped out at 42k miles - a tad premature!!) with things like CVJs, bushes, rotors, fans, dampers, springs, electronics etc lasting a shorter period as they are wear and tear items. In a lot of modern cars the electronics seem to be the weak point - but some owners never get a problem.

I guess it's fair to say that beyond 100k miles more of the 'expensive' items are more 'likely' to fail. Keep the servicing in line or better than OEM requirements and don't skimp on the cost of oils and key fluids and you stand a better chance of an 'X' lasting well beyond 100k miles.
