Three years 36,000 miles later, I still adore my TSX. Superbly reliable (great after my previous car, a Murano, got bought back under the lemon law), great gas mileage (avg. 30 miles per fill up) and a joy to drive.
The reliability and gas mileage. Love all the fun standard features like XM, sunroof, two driver seat memory, and homelink.
Honestly, none I can think of. At this point I wish it were bigger as I'm going to trade it in as I have twins on the way. I will sorely miss my TSX.
