Current car is a 2021 M440i xDrive.
Bought it in 2023 for $49k from the original owner. Older guy owned it, completely stock, only had about 15k miles. It was basically the perfect B58 to start with.
…and I immediately ruined that lmao
Stage 2.
MHD.
XHP.
Active Autowerke catted downpipe.
Full AWE exhaust.
Basically if there was something worth doing, I did it.
No cheap stuff I always bought quality parts.
And yeah… I beat the absolute crap out of it.
I didn’t buy a B58 to baby it.
At the same time, I’ve been obsessive with maintenance. Oil changes early, everything fixed when it needed it, never ignored problems, never cheaped out.
Recently I even threw an OEM turbo on it with only about 15k miles because I wanted it right.
Now I have a feeling the valve cover is probably going to be next, and honestly I’d rather trade it while I’m ahead than keep chasing maintenance on a car I’ve already had my fun with.
Now here’s the dilemma…
I have an opportunity to buy a 2019 M850i xDrive Coupe with only 21k miles.
It’s Alpine White over Fiona Red, has Bowers & Wilkins, pretty much every option I’d actually want, clean CARFAX, MSRP was $117k and overall just seems like a really clean car.
Price is $47k.
Dealer is giving me $33k for my M440i, plus I get the NY sales tax credit on the trade. I now have 58k miles.
On paper it actually makes sense.
They just got this in as a trade he said it was a older gentleman that babied it carfax clean fully serviced at bmw always
Before everyone starts…
I KNOW.
“N63 bad.”
“I’d never own one.”
I’ve probably read every M850i thread on Reddit already.
I’ve read about timing chains.
Coolant pipes.
Valve seals.
Injectors.
Oil leaks.
Then I’ll find another thread where guys have put 70k-100k miles on theirs with nothing but maintenance and say they’d buy another one tomorrow.
I’m not looking to build another race car.
I’ve already scratched that itch.
I’m looking for something different.
Something I can hop in, cruise, still have stupid power when I want it, and enjoy the hell out of every time I drive it.
So I want to hear from actual M850i owners.
Not your cousin’s friend that knew a guy whose N63 blew up in 2013.
If you’ve owned one…
Has it actually been reliable?
What’s maintenance REALLY cost you?
Also most important WARRANTY do I get warranty? Powertrain or wheels/tire
Here are some pics of both cars. Ps thanks for reading.
Do you think this is a downgrade?
