Greetings from Texas, I hope you're safe and warm during these freezing times.

I've had an E83 for 12 years and based on my experience I would go for the F25. The F25 had huge improvements in its interior quality and it holds up better than the E83.
Wheel Bearing replacements are easier on the F25.
The F25 has the ZF8HP transmission which is way better than the GM6L45
Safety ratings are probably better on the F25.

Good luck!
