Acuras are reliable, but they are the weakest of the luxury brands except for perhaps Buick IMO. The TL, TSX, and RL don't really stand out in any way against the competition. I'd go with Infiniti, Lexus, Audi, BMW, Cadillac, Mercedes, and Lincoln before I set foot in an Acura dealership.
I'm not saying they are "bad" cars, it's just they don't really do anything well. Lexuses and Mercedes are very comfortable. Cadillac, BMW, and Infiniti are going for the luxury-performance. Audi, Lincoln, and Acura are going after the technology stuff.
Audi has quattro, MMI, and their FSI engines. Lincoln has the Ecoboost engines and the most advanced automated parking system on the market. Acura really doesn't have anything that no one else doesn't have.
