Great Crossover SUV IF you can afford it
 I bought my 2007 BMW X3 3.0si with about 70,000 miles in January 2012.  I was 28 years old at the time and excited about my purchase.  It was a CPO and had a 6 month warranty with it.  I drive about 30,000 miles annually and at almost 185,000 miles 4 years later I am left to ponder whether it was a good buy or not or whether I would do it again.  The car I bought had a new sticker price of something close to $44,000, so considering that the first 5 years / 70k miles absorbed about $26,000 of that made me feel good about the purchase.  It was KBB's book price for a private party sale in Good or Very Good condition.  Now that I've put 115,000 miles on it I look back at the service and maintenance history and just as I was starting to get impressed by how little went wrong in 115,000 miles but then I hit about 182k and it needed a starter, then tires, then transmission.  Needless to say it's been a bad month or so in the repair dept.  Here's a list of what I've needed to have done from 70 - 185k miles at the approximate mileage:Every 10k - new oil and filter.Every 20k - new air filter, clean MAF sensor.80k - Water pump at approx.90k - tires125k - Coolant expansion tank was cracked and replaced135k - tires150k -  windshield washer pumps150k - brake pads and rotors.155k - ignition coils and spark plugs165k - fuel filter170k - changed brake fluid, bled brakes, new anti-squeal on pads182k - tires182k - starter182k - transmission fluid & filter, differential & transfer case fluid (transmission started slipping, don't believe BMW lifetime fluids get them changed every 30-50k depending on driving conditions and climate).185k - transmission (bought used with 99k miles for $1480 - a tad under $2700 after mechanic and shop fees)
