I spent some time between the two and the three reasons why I went with the M6 was that (1) there were too many TSX's on the streets, (2) the M6 fully loaded was cheaper than the TSX I had in mind and finally (3) I wanted a V6 under hood instead of a wimpy I4. I know that TSX is a very good car, but the final deciding factor for me was the fact that too many of my friends already had that car. I wanted to go with something no one else had at my school, and so here I am with my M6 happier than ever.
