I road tested the TL last year and then immediately went down the road to the Honda dealership and tested the accord V6 EX coupe. The Honda felt too light compared to the Acura.
THe next week I went back to the dealer ship and took out the TL again and then immediatly a TSX. I did not feel any inferiority in the TSX except for the fact that it was only 4 cyls. The TSX felt nicely weighted.
I would look to the Acura line up.
