Had the car about a year, and my wife hit a deer with it. The deer struck her on the driver side window, and its horn left a mark all the way up the window that I cant even buff out. However I feel that any other window would have busted and my wife would have had a deer in her lap.
My first BMW was a 1987 325e and it ran perfect for 280,000 miles other than normal maintenance. At 280k the coil burned out, I put a new one in and 2 weeks later and the same thing happened. I tried one more time and the same problem so I sold it DOA. I bought a 2004 BMW 330Xi with 59,000 miles on it. My car now has 99,000 miles on it and here are all of the items I replaced. Complete CCV cold weather kit, Crankcase Vent Valve, Oil Separator Hose, Breather Hose. Valve cover gasket, valve cover, power steering pump, spark plugs and coil pack, rear springs, cv joints, DISA, multiple alignments because of pulling, brakes, and now it has mustard color under the oil cap. Updated 4/1/2016. I finally traded the car in to dump this lemon. It ended up having a bad head gasket. The car was never overheated and the antifreeze was rated for well below temperatures we have in Wisconsin. During the winter it would suck down the antifreeze. Not worth all the trouble and I will have a hard time considering a BMW in the future. I replaced it with a Honda Pilot and the Honda now has a 125k trouble free miles on it.
Great car to own and drive. Yes, there will be repairs after 100k miles, but I got past 200K before having to replace the clutch. Most other repairs have been to structural parts - engine is just unbelievably superb. I drive in snow and mud, with pets, groceries, gear, etc. Gas mileage has been a solid combined 25 mpg for the life of the car. If you can find a used one, you could probably get a decade out of it and love every minute of driving it.
The 2004, BMW 325i is the most reliable and aggressive engine of the 3 series BMW line. I purchased the BMW in Heidelberg, Germany brand new in 2003 October. Since then, I have not really spent any money replacing or changing mechanical parts, except for the rotor, shocks, struts, and of course the occasional oil change. Driving this vehicle is a dream. At 100,000 miles, I just got the transmission and differential oil change. For $36K, it has been the best purchase of this magnitude, ever. The only bad thing about the 2004, BMW 325i is the interior is made very cheap. Stuff start to fall apart after a few years.
This is my 4th BMW that I owned and the best one by far. What makes this car different from others is the ZHP package or Hight Performance Pkg which give it different look and options. O owned it for over 4yrs and never had any major problems. I purchased it with 44k and now has around 80. Maintenance on it cost me around $1k per year including oil changes and Michelin high performance tires. Car came with HID headlights, leather, navi and all available options.
