I was down to this and the VW CC and made the wrong choice. It's a nice car, handles great, but it's underpowered with the 4 Cyl automatic especially when entering a freeway. Even in manual mode it's inadequate in the all important 40-60 range. If you are thinking of switching from a 6 cyl to the TSX 4, think twice. The TSX had better features for the price, but when you step on the gas at 40MPH and nothing much happens, features don't help. The 6 cyl was $3,000 more (too much). The VW has it where it counts, low end torque. Unfortunately, the VW came only with leatherette(Vinyl) and my wife hated the VW drving position. My guess is Acura will change to the turbo 4 from the RDX next year.
Handling, seats, paddle shifters, features for the price.
More Power (switch to turbo?) and 6 speed automatic.
