Having put only 200 miles on the car, in the little over two weeks I've owned it, I can't say the fact nothing has gone wrong means very much.
After four years in a Prius, I'm wowed by the pep of the TSX. I'm under-wowed by the gas mileage: I was getting 47mpg with the Prius, I'm just below 22mpg with the TSX.
The interior is posh; it compares favorably with the Q45 I owned from 1991 to 1996. Technology having advanced, it has a good many more bells and whistles than the Q -- including blue-tooth for my phone and an MP3 connection -- and its sound system is also better than the first generation Q's.
I'm sorry, but you can't compare a hybrid vehicle like the prius to a premium 200hp Sport Sedan. You'd have to compare it to another car in its class.
