Mein Auto: 2007 BMW 550i
I've HEARD people say the 550i engine is much more reliable. Personally I drive a 2007 550i and I LOVE IT! I went CPO from Niello BMW and got a great deal because they wanted to move the car that day. I've never had serious issues with either the SMG or the engine. The biggest issue I had was replacing the water pump @ 95K, which seems to be a common issue, when I looked into it. Don't go 15K in between oil changes, go 8-10K depending on how hard you drive it. The engine is expensive to fix, and some preventative TLC goes a long way, I want mine to last past 200K. Go with the 550i all the way, better engine and upgraded interior, the 2007 550i has upgraded interior and the CPU is from the X5 and it looks cleaner and nicer than previous years, closer to what a 7 series looks like inside. You will feel the power difference and it's worth the extra cost. When the tire tread wears down, replace with Conti DWS or Michelin Pilot Super Sports or Bridgestone 970AS. Have fun!
