Jaguar XF
I don't even like the XF all that much, but the LaCrosse is terrible. It's hideous, not very luxurious, and just cheap looking. It has a lot of "wood" through out the interior, but it just looks like good quality plastic.
I can't believe Buick is actually trying to compete with brands such as Lexus, Mercedes, and Jaguar.
If you could afford a Jaguar, you'd be an idiot to buy a Buick. especially now that Jaguar fixed their reliability problems.
