I purchased mine as a CPO with 33K original miles on it. IMHO all the dealer did to "CPO" the car was to detail it. Within the first 24 months it had the following major problems: 1. Power door locks failed 2. Right rear wheel bearing went (was bad on delivery...CPO people were obviously deaf) 3. Electric water pump failed 4. Low oil level warning light came on less than 500 miles after purchase (further proof CPOing ignored that 5. Radio display not visible while wearing polarized lenses..oil leak, battery died, bluetooth not blackberry compatible, outside mirror motor failed....brakes stick on release....
After reading all the hype about how wonderful the BMW 3 series are, I purchased a very low mileage CPO vehicle. First, the great looking sunroof is absolutely useless as it is so noisy at any speed above 10 mph, you can't use it. BMW says "This is normal." The speedometer is off by about 5 mph at freeway speeds. BMW says "This is normal." I have a Volvo and a Ford with similar sunroofs and they are quiet. And the speedometer on all my other cars (Chevy, Ford, Volvo) are accurate. BMW touts their cars as having superior engineering, but that is obviously a lot of sales hype. I am looking forward to the day I can trade this one in on almost anything else. Very disappointing car.
This review is for the wagon. I like putting my bikes and camping gear in a fun car but don't like SUVs for many reasons, so sport wagons are perfect. I had leased a 2007 A4 and really liked it but the 328i is simply a better car. It handles much better (except in rain of course), has better interior ergonomics for a tall guy, is faster in most scenarios, is quieter, more reliable and gets better highway mpg. Both are great looking in and out. The A4 seats however have much nicer, softer leather. I average about 23 mpg, maybe 1 mpg better than the A4. But I do much of my driving on the highway where the 328 gets 29 mpg while averaging 72 mph! Overall, a fantastic car.
Make sure you have the car completely checked out if you are buying used like I did. Make sure there are new spark plugs, and the ignition coils have been replaced. The car leaks oil a bit and I had a window regulator fail, but all are fairly inexpensive and easy to do. Do not go to the dealer for these things. You can do them yourself with little knowledge and you tube videos. Also, my windshield fluid pump failed and I have yet to replace that but here in SoCal, not much of an issue milking that repair. Regardless, check you tube first. Almost all of the repairs can be done by you.
Notwithstanding the following, the 328 Touring is great automobile, but in the hopes that these comments may come to BMW's attention, here are five criticisms: 1) the rear hatch requires some effort to open; 2) the direction signal is overly electronic and can miss the off position; 3) the radio control is based on some old DOS format and is awkward to change from cd to tuner; 4) the car produces a large clunk over potholes; 5) the transmission spends so much time seeking gas savings it's slow to down shift (and the sport mode is way too nervous). These should be all easy to correct. But perhaps most disturbing is that the car's ride is drifting towards that of Lexus and away from BMW.
