The dealer would NOT allow us to take on highway; now I know why. The ride is so bumpy that you feel sick to your stomach. We can't get the sports suspension changed because it will cause the warranty to be invalid. I should have walked away after being jacked around by the dealership with agreeing to match printed price of others; and then hemm & ha for 5 hours trying to figure out how to get out of that one. I should of, could of, and didn't; so now I'm stuck with a vehicle that makes me throw up on bumpy highways or gets us dizzy.
