2001 BMW 3 Series Sedan 330xi AWD 4dr Sedan (3.0L 6cyl 5M)
Looks great but is always trying to break.
 I bought this car in 2014 on June and boy was i happy. Loved the looks and performance. IT was always polished and detailed once a month since the start of time. 2 months after buying this from BMW dealer from a one owner the belts and pulleys went bad. I Took it to the shop and had it replaced with the OEM parts. "Note i only did OEM replacements for everything your about to read." My shop during the repair found out the front axel had gone bad as well as the engine mounts and transmission mounts. Reminder to those reading my shop is a very reliable shop in the Bay Area with 100+ cars a day. So after finding out bought the new axel with the mounts right away. Drove the vehicle for a month and everything was ok. Winter night decided to go get a Starbucks coffee before i took off to go flying, "reminder i am a pilot". As i walk back i notice severe smoke coming from the hood. I popped the hood open the and expansion tank was cracked. I had the car towed to the shop and had that changed right away. As they where checking the saw the hose was bad as well as the water pump and the radiator looked as though it was ready to go. Ended up replacing all the parts right away thinking id keep the car still. A month goes by after all that and i get a check engine light after driving from Los Angelas. I diagnose the code since i use to work on cars at one point and it was the O2 Sensors. Jeez Lucky me it was the month i had to smog the car. Again back to the shop and had the O2 sensors replaced. Very expensive. After driving back from the shop i notice smoke again from the hood. Look under Valve cover gasket was bad. Turned around and left the car over night till they replaced that. I drive the car for two months and again smoke from the hood. I check and again valve cover leak. I take it to the shop and it was not the cover but the valve cover its self that went bad. $300 is the cost of that cover. I said screw it ill deal with it. YES the valve cover was torqued correctly when i had the gasket changed. Another month goes by and on the free way i get a check engine light and the car down shifted harshly to send gear from 4th. Found out the alternator went bad. Ridicoulas. I was about ready to destroy this car. Note i did change the differential fluid and the transmission fluid right away when i bought the car due to this generation having transmission problems on the automatic version. 3 months or so went by from all the BS and i decide to go to the snow with my new continental DWS tires. When i got on the freeway and got close to lake Tahoe and to the snow the steering wheel got very very heavy.... Power steering killed it self. Regardless since it was gone i was already in the snow. Drove it and ill say despite not having power steering this car handles amazing in the snow. So when i got back i poured a temporary power steering fluid fix. Aprox a week went by when i put the fluid and i was rear ended by a jeep in traffic and i hit the car in front. The impact was very hard. The winch on the jeep hit me and i damaged the impala in front. The front didn't have a scratch beside the license plate frame damaged on my car but the impala was damaged from behind. The back bumper had a hole but over all it was a hard hit and it coped well. Two months later sold the car with bad power steering and shocks. Never again buying a new BMW. Now driving a 2006 C55 AMG Mercedes. Ive always owned Mercedes and never again will i buy a bmw. My relative had a 1994 318i and that was bullet proof, close to 400,000, parts original. Other relative 2000 528i with 340,000 miles. It was also bullet proof. Both cars great. Other relative had a 2004 530i and had problems with tranny and electronics. 2006 325i electrical problem. 2008 750li electrical and engine problems. Overall BMW is not the ultimate driving machine and they are problematic. I SPENT $6,000 in repairs in a little over two years! IT DID 14MPG combined. Only freeway it did 25MPG. WORST DECISION IVE EVER MADE BUYING THIS CAR!
