I love my 325i (2006 E90 in the US market it was called the 325i only for 2006 but it's nearly identical to a 07-08 328i) but it has very high mileage and it's an automatic, and my kid will be driving it soon (bought the car for a *very* low price to teach him how to repair cars, to do maintenance, and learn to drive on it). I love the car so much I want one just for me, but cleaner with less mileage and a manual transmission.
The N52 is plenty of enjoyment for me and I appreaciate the simplicity, but I have seen many 335s in the same price range I'm looking at for similarly equipped 328s. I'm leaning towards sticking with the N52, but what would I be getting myself into with a N54? Assuming it's been maintained well with oil changes done properly, just how much extra work are these to keep going?
I'm aware of the charge pipe issues, high pressure fuel pump problems, injector issues, wastegate rattle, seals in the turbo (not really unique to BMW), and the required walnut blasting. Other than these items, are they really that much less reliable than the N52? Is it guaranteed that the turbos will need to be replaced when they start to see very high mileage, or is it possible for them to actually not fail for the life of the car? Can the N54 make it over 300K miles like the N52?
I'm leaning towards keeping it simple and sticking with natural aspiration, but for the same price I am tempted by the idea of having some serious power available, even by today's standards.

I have a 2008 e90 335xi that I got used with 17k miles in 2011. By 2012 I was FBO with 45k miles on the car. Today I am at 179k miles, I love driving my n54 more than my P3D+ tesla with Free unlimited supercharging.
