There are tonnes of threads on this. B58 is great. Recommend taking a look at Bimmerpost for common issues which are very little with B58 depending on the year you’re looking at buying.
Mine is 2017 first gen B58. I’m at 113k kms which is just past 70k miles. Car’s been great. Love it and mine is fully optioned which I do recommend. First gen had expansion tank issue which I took care of and the front air flaps which under warranty for 15 years as it’s been a common issue. Mine appeared on 2021 and BMW took care of it. Other than these two just the maintenance was my cost.
