530XI or M35X and why?

UPDATE…
Infinity is gay.

I have to get more details but my dad tells me every time he takes the car in it costs him more money.

Right now the car is in because it has a bad wheel bearing at 22222 miles!
I assume it won’t cost him anything but you never know at this dealership.

If you buy a BMW isn’t EVERYTHING free for like 3 years?
