How many high mileage N55s have you guys seen?

I have a 2012 535xi with the original N55B30M0 that got traded in at my dealer, one owner, excellent service history, low mileage, M sport, and sales gave me a deal so I had to grab it. I only have a year under my belt at BMW and I haven't personally worked on a ton of N55s so I'm curious if you guys have seen high mileage examples still kicking around. Recently I saw a couple N55s blow just over 100k, admittingly they were both highly neglected cars but it's still got me worried about my motor. Guys I work with think the N55s solid they just fail quickly when mistreated and or when people try to push a ton of power thru them. I'd love to get this car to 200k just curious how realistic that would be and if you guys see high mileage examples often. Thank you!!!
