LOL that shouldn't change the ride quality, but carry on

 

Oh, but it does.

Every impact on one side now transfers some of its force to the other.

 

Drive both. Then decide. The Sport is a fair deal for the extra stuff you get, I think. But if you only want ONE of those things, then I would not say it's worth it.

Especially since I don't think the stereo on the Sport is particularly excellent. Good? Sure. It's perfectly fine. If you feel audio quality is very important, however, you should seek out a car with a higher spec stereo and a quieter interior. Hope that helps!
