It seems like you've made up your mind about which car you want but I'll throw in my 2 cents for the 128/328 comparison.
First of all, you want a coupe - the e92 328i is a coupe (e90 is 3 series sedan) as well as the 128i. The 328i coupe has a longer and slightly wider wheelbase though it weighs ~100 pounds more than the 128i.
The 328i is going to be a little more spacious and luxurious but will lack the sportiness of the 128. I shouldn't say "lack" because the 328i is still a sporty car - it just isn't quite as sporty as the 1 series.
Here are the exact curb weights:
128i coupe = 3252 lbs
328i coupe = 3351 lbs
328i sedan = 3362 lbs

I chose an e90 335i simply because as you can see the weight difference of the 328i coupe vs. 328i sedan is minimal and I wanted the added space of the sedan.

The HPFP is an issue with the n54 twin turbo engines (found in 135/335/535i) and I would be worried too if I didn't have the 10 yr / 120,000 mile extended warranty. However, the turbo's generally don't have any issues and even if they did you could outsource the parts from here in the US - or where ever you can find the best deal. If you learn to work on the n54 engine on your own its relatively inexpensive to maintain.

You seem interested in a sporty car and if that is the case, the 135/335i is definitely worth the extra money and higher risk. The n54 engines are truly a blast to own and drive!
