Early days, but considering one of these.
It'll be a 116i, 118i or 120i. 4 cylinders. Performance is not an important criteria; reliability and economy are.
I know well enough to stay clear of the N42 engine, but that doesn't apply. The models we'd looking at would have either the N45 or N46 engine; I seem to recall that the N46 isn't especially great, either, but I know little of the N45. I understand the timing chain needs to be looked after/replaced, and that VANOS can cause vibration. And that using **good** oil and fuel are very important.
Any thoughts? Other than the engines, what should we look out for? Any longer-term owners have experiences (good or bad) they can share?
