I test drove the manual and the auto. The manual is the one to get. I find my TSX fairly entertaining to drive on windy roads and yet very comfortable and relaxing in the highway. The interior is a nice place to be; the seats are exceptionally comfortable. The engine is refined and is powerful enough to be fun with the manual. It is only at speeds above 60 mph where it cannot compete with the smoothness of a good V6. I'm impressed with the fuel economy, 31 mpg. Quality is excellent, I have not found a single rattle or manufacturing defect.
The seats are excellent. Their level of equipment is very good for the price.
The key is not special enough for a premium brand, it is 10 years behind the Europeans. The carpet in the trunk could be nicer. The iPod interface is somewhat harder to operate than I would like. I would like more interior color options on the manual.
