Hey everybody I am new here on the forums. I do not have an STS yet, and hope to get one within the month. I want to get the all wheel drive and a 6 cylinder. Navigation is a must. Just wondering how everybody likes their STS. Other cars I was considering was an Audi S4, C Class Mercedes, and 3 Series BMW. I think the STS is a much better car overall. I would like to know more about the navigation system. Is it touch screen? Ipod compatible? Thanks!
