I FAFO’d by not getting a M550i and now I have deep regrets as I didn’t know BMW would discontinue it. The G30 540i ran great for me and is a brilliant car, but I really would like to try a V8 before they go away. I guess I could look into a used one, but I suspect these get driven very hard and I wouldn’t be confident in long term reliability unless I bought it new.

Please hop into r/personalfinance and ask there. Post your income, savings and so forth.

The most common issue I see is coolant leaks. CPO does not cover the hoses and that is what usually leaks. It can be about $600-$1k for that repair if you cannot DIY.

Personally I would avoid the CPO premium and self-insure. So many complaints on forums now about CPO failing to pay out.

I also suggest learning to DIY basic maintenance. The X3 is surprisingly good in terms of ease of oil changes, spark plugs, brakes and so forth.

Damn. That’s not even that old, or that many miles.

First, in most cases, it’s technically not “runflat” anymore but rather run-on-flat, which is a standard Mercedes Benz came up with to try to strike a better balance between comfort and run flat capability. It can only do 50 miles at 50 mph I think whereas true run flats were able to do more.

In my experience there’s still a lot of stigma around true run flats from years ago, which truly were horrible. But these days, the suspensions are better and the run-on-flats are much softer. A lot of the folks that knee-jerk respond and tell you to ditch run flats may not have ridden on the latest generation of cars or run-on-flats.

My personal take is that for the higher profile tires (like yours) where sidewall is decently chunky, the difference is not that big. This is based on personal experience with my own swap. However on lower profile tires, the difference is more noticeable. This is based on two swaps I did on a 5 series. I swapped my 20s from ROF to regular, and I did the same on 18s (I’m kinda obsessed). With the 20s the difference was huge. With the 18s, I couldn’t really notice a difference in comfort between ROF and regular b

I’m a Mazda fan and remember my time with Mazda fondly, but all of this is marketing BS. They have bean counters that rule the day, just like everyone else.

Oil filter housing looks cracked.

Subtract 500 miles from your next oil change marker :)
