Turbo I4 vs N55

Hi,

I am planning to get a 2012 F10. I like the 528i because the N/A has more linear power and better reliability. Too bad BMW discontinued this one.

For 2012, in the US, we will have Turbo I4 or N55. Which one is better in term of reliability? I am worried about HPFP failure.

I might have to get 535i because from my understanding N55 (which is similar to N54) has been around since 2007. I hope they will have figured out most of the bugs by 2012.

Let me know what you guys think?
