2008 Si owner, still love the car, fun to drive and 0 problems after 2 years. I had driven a friends 2008 Cobalt turbo, and found it fast and responsive, but just not "my" car. Maybe if I was 10 years younger, lol. Did have trouble seeing out the back window, with the high hood and spoiler. Would have needed to keep an eye out for the law

The other thing that sold me on the Si was that it was the only car in this class that was "made in Canada"

The Cobalt was made in Ohio, GTI in Germany, Mazda 3 in Japan.
Not much new in 2010 Si, it seems. Some trim, (previous) options now standard, and some new colours. Did Honda put some "real" tires on this model? The all-seasons on the 2008 weren't good for much, and really pooched the handling of the car. Summer tire = good, winter tire = good, all-season = mediocre.
Really curious what the 9th gen Si is going to be...
