I am buying a new car. I currently have an'04 Sienna van with 80,000 miles on it-my 17 year old daughter will drive that mostly. Originally, I was looking at the RDX because I didn't want to have two big cars. It sounds as if the MDX is a lot nicer than the RDX, amenities and ride. I need help figuring out which Acura to get, or if I should look at the Lexus RX 350 AWD. I live in the Boston area so need something that is reliable in the snow and don't want to get snow tires. Thanks for your help.
