Loved the car, had the oil changed two months ago and the level indicator in the iDrive, plus the low level warning both failed to indicate that oil had leaked out through a failing seal. Level showed nearly full and checked it every time I fueled. Heard a knocking one day and then froze on the highway causing a major safety issue, towed it in after getting stuck in a construction zone with no spare lanes, the shop said there was only one quart of metal shavings oil left. Car needs a new engine at 160,000 miles. Huge mistake taking the dipstick out of the car. This is a huge mistake on BMWs part. My last 528i got 220,000 miles before trade and was as good as new.

I own a repair shop, so I did the repairs myself. Be careful buying from someone that did not maintain the engine. The engines will build carbon deposits on the intake valves. The injectors need to be updated. If it has an oil leak at the filter housing, have it fixed it can cause the drive belt to come off and get sucked into the oil pan . That is expensive to fix.
I've owned a lot of Bimmers. The E60 5-series 550i is my absolute favorite. Very composed and agile for it's size, it comes with a screaming 4.8l V8 good for 360HP (or about 500HP if you put an ESS supercharger on it like I did). I have owned mine for three or so years now, and the only issue I have had is with an intermittent clock reset due to a failing comfort access door handle. It is roomy, smooth, and comfortable for those long highway drives, but one must constantly be aware that the car tends to want to cruise at it's comfort zone of around 85MPH - i have had many occasions where I am doing the 65MPH limit, get distracted talking or listening to music, and then find myself at close to 90 when I look at the speedo again. The car is near silent and rock solid, so you really don't get the normal cues that you are speeding. Gas mileage is the Achilles heel of this car, though. I averaged about 15-16MPG in normal combined driving, which would drop to 10-12 if driven hard.

where do i begin? its a POS. in the 3 years i owned i cant say its a high performance vehicle because i have ALWAYS driven it with an existing problem. usually two problems at once. started with the tires that came on vehicle, factory recommended run flats that were causing vibration, did alignment, issue continued. replaced tires, issue went away partially because the boots needed to be replaced. water pump failed, flat bed truck towed, $$ thousands later, intermittent power reduction while driving, replaced two spark plugs and two coil overs, valve decarb recommended, replaced two spark plugs and two coil overs, no you're not seeing double, nor triple because power reduction again, and rpms all over the place, replaced both bank 1 & 2 turbos, $5k to find out it was the clutch (its a 6 speed manual) not the turbos, dealer could care less. i've never seen a car leak oil like this, its ridiculous, they replaced the oil housing 3 times, pretty much every oil change you replaced some major part. another power reduction issue caused by broken gasket, replaced that one too. this car promises 300hp, it never delivered because it always had an issue. the boot of the car contains all the electronics, a water bottle i had in trunk leaked and again power reduction, vehicle undriveable, $1100 to fix tpms sensor, like what does that have to do with engine power. and they had to reset the whole car. battery replacement $500+ has to be programmed. i swear they didnt make any of this up the dealer, but they might as well have. read around all 2005-2010 bmws have major issues like this. the list goes on, but i am at a loss for words.
