well, i drove an 04 and now own an 05. from a personal, seat-of-the-pants feeling, the 05 feels like it pulls stronger. however, i don't think it's very noticeable until higher speeds (70mph+). what i've discovered in the past is that if you start with a high hp number and then add more hp, it's not really noticeable until higher speeds (i modified my 300zx twin turbo from 300hp to 396hp and couldn't tell much of a difference until i got above 80mph, and then it was a huge difference). i think that's probably why the new mustang is close to the gto in 0-60 and 1/4 mile, but if you look at the 0-130mph numbers in C&D (or was it R&T?), the GTO is 9 seconds faster. it's also why some of the little cars with low hp can keep up with the GTO until about 80 or 90mph. i don't really care for stoplight-stoplight racing because lots of cars are fast off the line (especially if they're AWD) - it's more fun to see their faces when they pull alongside on the interstate and think they can keep up only to find out they're in the minor leagues.
