I've rented the 3.5 v6 and was OK with it but not impressed. I bought a 2012 V6 pentatstar because I was very impressed by it and I commute a long way so the mileage was a bigger issue. It hit the sweet spot of decent power, mileage, and the ability to haul my family around in. And I think it is the best looking car on the road. I have not regretted it a bit. Opinions are split on the 8spd ZF transmission, but I think it is a big improvement on the V6. It does try to keep RPM low for mileage and so it is different than a 5 speed and will drop a couple gears to pass. I ocaasionally just drop a gear manually by hitting L and it picks up to pass nicely.
