FuturerGS300

Any news on the 2007 GS300????

OK... looking at getting a fully loaded GS300 within the next week but I have a couple of questions: 1) I really like the look of 18" Tires but the sales rep says that the 18" tires have a rougher ride and that they "track" more on the freeway? Does anyone experience this? Is this noticable? 2) I want the ability to use my bluetooth cellphone and my car to be able to dial a number by voice... is this possible? The sales rep said no... that would make this car the only one not to be able to voicedial by number... infiniti...check...AUDI yes... That's it... Thank you.
