Did you buy it because you wanted it? I would think it would bother you what they said, only if you're not happy with it yourself.
In that case get what you do want the next time around, mines not a Si and I love it.
As Bob Marley(I think) sings "Don't worry, be happy".
I don't care, I laugh and usually say what fun about going fast in a straight line, I love corners and my car is setup for that...
When I bought the car I needed a car badly so I didn't care, I would just make the car to its strengths, with the gas prices now I am very happy with my choice...
