How fun! Shifting into sport mode makes this car fun. Lots of compliments. Has a surprisingly nice growl in the cabin when accelerating. Love the panoramic roof and leather interior. I got mine used....bmw owners generally maintain their cars above average so if you can find a low mileage model just out of warranty, snatch it up and you won't regret it.
I have the M Package and it's worth every penny, is gorgeous and handling is superb.
Acceleration is go and no breaks down. Gass is normal for a 6 in line. I have owned for 1 year, buy it used with 119k and now after 10k, I have to say it's still running like new, my wife love it and it drives like a sport car, it turns very good and breaks/stop almost as my M3. Very safe on the rain or snow due to its awd.
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 - tires 125k - Coolant expansion tank was cracked and replaced 135k - tires 150k - windshield washer pumps 150k - brake pads and rotors. 155k - ignition coils and spark plugs 165k - fuel filter 170k - changed brake fluid, bled brakes, new anti-squeal on pads 182k - tires 182k - starter 182k - 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)
So being the spoiled 16 year old that I am, my parents surprised me with this car before my birthday in December of last year. I absolutely love my car. When we bought it however, the radiator was busted and it was making some kind of ticking noise. We got that fixed. We kept the car in service and I haven't wrecked or anything. The car's rear tires were worn down when we bought the car so we replaced them. We didn't know at the time that when you buy an expensive car the the front and rear tires were two different sizes. So it messed the transfer case up. When they replaced that, the towing company bent my steering rack which is now throwing off some lights and one of my O2 sensors needs to be replaced. My local BMW dealership told me that once you replace one O2 sensor that you will have to replace the others, which I found out is a lie. But I also had my oil pan replaced, (it had an oil leak when we bought it), and I wouldn't recommend taking it to a place that "specializes" only on foreign made cars. They charged us $2,000 to fix it. One of the parts only costed $35 and the labor was $800. Other than what all has happened, the car is an outstanding car, I honestly don't want to get rid of it. I have 4 siblings. One is a baby and the car is able to fit his car seat in it just fine! The interior is amazing to clean. Mine is white with tan interior and it is easy to spill things on it. But it is also easy to clean. I absolutely love my car and I would recommend it to anyone.
