F30 n55 Reliability High Mileage (150k km/90k miles+)

I have seen a couple threads about high mileage but for me those are not high enough. I want to know about owners who have actually owned these cars specifically the n55 after the warranty ran out. I searched a bit but could only see what to me is not high mileage.

I am looking to get a 335 myself and just want to know what I'm getting myself into before I buy as I drive a lot. I put 50 k km in one year on my current car. I will be keeping the f30 for quite a while so I want to know that it won't blow up on my by the 2nd year of ownership especially as I plan to go FBO as well so please drop your reviews it would be much appreciated!

You will need to replace the plastic charge pipe as it has a tendancy to blow even on stock cars due to flawed design. There are plenty of steel ones you can get that will last longer and resist cracking.
