I drove a S model. I'm going to go with a EX AWD in white with trailer package. I want 18" wheels and the EX has most of the stuff I want and it's got the second row bench that lays flat. About $6K cheaper than the SX Prestige.Welcome to the forum, glad to have you on board. Did you get to test drive a model in the spec that you are leaning towards? Options on lots seem to be pretty limited.
I was told the 20 are much more expensive and ride is not as good as well as gas mileage with 20". With that said I'm still going with the SX prestige package.I'm curious why you want the 18s vs the 20s?
I haven't compared them, but I know sometimes the larger wheel/tire packages have better handling but harsher rides.
