I actually laughed when I heard Buick was competing against Lexus and BMW.
If you choose Buick over Lexus and can afford both, you're an idiot. The Buick isn't even much cheaper, only a few thousand dollars. On a $30k car thats not very much
It's also funny that they have to pick on the "worst" Lexus (the ES350) to even make it look comparable, and Buick still doesn't win.
Buick should compete with Mercury and Lincoln. Not Lexus, BMW, and Audi.
