I havent driven the Infiniti, but i have some information for you..TL is better on gasfueleconomy.govAcura has better resale and reliablity (Infiniti's are great too.. but acuras ARE better)You can call Acura and Infiniti's "parts department" and ask them how much it costs for suspension, AC, CV Joints, etc.... (just to find out which one is most expensive to maintain)But in the long run, you want to buy something you will like... and i think BOTH options are pretty good...And the FWD on the TL is very nicely done (ive tested a few of them) - Go test them both
