For me, I decided that if I was going to mod a Sport with not just bigger rims and tires, but also Rubi suspension and shocks, that I would just go ahead and get a Rubi. But that's not my plan. I plan to stick with stock wheels, get slightly bigger tires, and that's it as far as big mods go. Plus, I don't plan on doing any real off-roading, so the Sport S makes the most sense for me. In my opinion, if you're only spending a couple thousand more dollars on a Rubi than a Sport S, and all of the additional money spend on a Sport comes standard on a Rubi, it's probably a better value to get the Rubi.
