You're right. it is a stupid acronym. For ages i knew that it meant facelift but never knew what it actually stood for.
My advice regarding the pre lci 330i is simply to avoid the N53 engine. There may have been some cross over with the N52n in post lci, i'm not certain. All I know for certain is that if you go for a pre lci model it would have the more reliable N52 or N52n engine.
With the above being the exception I feel the post lci cars are generally better. As I say the suspension is much improved so they do drive a lot better. BMW managed to reduce emissions across most of the cars for cheaper tax. Therefor if you want a 330d then post lci will be better. only get one if you do the miles though, otherwise fuel bills will be pretty nasty and you will definitely get DPF problems. This is about the only problem i've ever read people having with the 330d and it can actually be fixed relatively cheaply while also improving the car by sticking the Ecotune DPF delete pipe in along with their tuning box which also codes the DPF out for you.
