Eh, their reliability is much worse than other brands, even luxury brands.

If it "works" it's great. But, once out of warranty it can be expensive and delayed before you can get your car fixed. On my S, I had to replace 3 door handles, drive unit, screen, TPS, passenger mirror was replaced, and a few other things. This was ~3 years of ownership and < 30k miles. Many of these things had a long delay before they could get fixed. I was in a loaner for over 3 weeks while they fixed the drive unit.
My father had an X that got bought back due to never being able to fix the rear door sensor. It would open a foot and freeze. He also had a handful of other issues. This was in less than a year of ownership.
My neighbor with the 3 got into an accident. It's ~6-8 months for them to fix their rear bumper. Additionally, one of the seatbelt adjusters and one of the AC vents rattle. So he stuck a piece of foam in there. His charging port has frozen and needed a manual release. And he says the screen sometimes doesn't come on. The nearest dealership is 100 miles away. He got an appointment, drove, got a loaner, drove home. They were 'Unable to reproduce' the rattles/screen issue. So he had to drive back and pick up his car with nothing getting fixed.
