On your own opinion which of the 3 would you buy?

As for the serious point of this question. Which one is the best buy in terms of reliability and maintenance cost? I'll be getting a car barely used(30k miles and down) my price range is 0-35,000 and I'd like a nice Luxury car.

I plan on doing a complete car audio system in the car I get to. If that has any matter on the question.
