After nearly a year, I'm still very happy with my TSX. It was the best blend of features I wanted at a great price (i.e., handling, fun to drive, good fuel economy, safety features). It moves well and emergency handling has been great. It's also a good size for city driving and has all the oomph I need. I'm appreciating it more and more all the time.
Handling, fuel economy, great brakes, interior looks. My experience with the dealer maintenance has been excellent (only routine oil changes needed).
Bit noisy on certain road surfaces and needs an iPod interface (taken care of in the 09s I believe).
