So Im pretty sure im either buying a 323i or a 328i, they both have all the same components minus the obvious engine difference. Point being, at a 50k mile mark what is actually known to break. Because this is going to be a private sale and not through a dealer, so no real warranty
50k range - things I'm aware of, and have experienced some of em:
Suspension (possibly - depends on previous drivers driving pattern, drive it hard or ask to be taken on a hard drive to see how it feels)
Brakes (If it hasn't been done yet, 50-60k is usually new pad/rotor time)
ATF Pump hoses. Known to leak, I sprung a leak few months ago, hose replaced.
Power window regulators - 4-5 years is when they start to fade. I've had one 'explode' in the door, and another headed to failure soon.
Camshaft sensors. Been told they tend to 'flip' after 5-6 years. I've had one go out - replaced.
Control Arm bushings - can begin to go bad anywhere from 30k-60k miles. UI'm in need of new bushings myself. Not very expensive, I suggest aftermarket bushings, the OEM ones are prone to failure, the aftermarket ones are prone to lasting..
You can go 'oem' aftermarket or 'racing' aftermarket, it's a 'ride' choice. (squeaky and tight, or silent and a little 'sloppy')
Around 60k is your I2 inspection, be ready for that in a few months after purchase.
That's my almost 2 year ownership experience. Basically not bad at all for a 4 year old car. Hope that helps ya out some.
