I am considering the purchase of a 2016 Buick Lacrosse in the Sport Touring trim. Obviously, I like the car but I am concerned about two issues: 1. The 3.6L V6 performs well, but not super. Without going way up in price to a 400 bhp vehicle, is it realistic to expect more power from a similar car in any brand? 2. I have spoken to a few people who like their Buick "OK," but not sure they would buy another one because of minor, but continuous, mechanical issues - such as, the AC going out; the emergency dash light coming on for no reason; etc. In your experience does the Lacrosse have a good reliability record?
