I had a '12 TSX. Even though I have a "better" car now, that TSX was my favorite. The TSX was designed for Europe and built in Japan and while there is no difference in powertrain to an American-made Acura, the ride, handling, and especially quality of the interior are a step up from the other things the brand offered at the same time.
If you're looking for a 1G, 2006+ is the right call. That was the year for the MMC where, not only did they tweak the appearance, they made notable adjustments to the chassis/suspension.
