re: BMW vs Lexus vs Mercedes vs Acura vs Infiniti vs Audi for four door sedan

The values of and ratings for these luxury models vary over time. Audi’s used to be performance alternatives to BMW, but were very unreliable. Acura’s were the most reliable cars on the road. Now Consumer Reports recommends every Audi and almost no Acuras. Mercedes remains one of the most overrated products of this century. Over engineered and you should get your own mechanic from Germany when you buy one. Lexus seems to be the one constant overtime. Most reliable, best design, value, and 100% made in Japan. Quality. (And, no, I don’t own one.)
