Nissan Quest is not SUV. Quest is considered a van.
you can check out some "popular" choice and see what you like
Lexus, RX350, Land Rover, Discovery BMW X3, X5 VW Tourage Infiniti FX35 MB ML320CDI (This is more expensive) Ford Escape, Explorer Lincoln MKX and many many more.
it really depends on what you are looking for. Do you want more comfortable ride? or more off-road ability? or other special need.
Personally, i think big moon roof is very important. so the choice will narrow down to like 4 cars. RX350, X3, X5, Discovery.
