For that price you can get a pretty nice Tahoe/Suburban/Yukon, or probably a very nice Aviator or Navigator as well, assuming you're looking for more than 5 seats. The Dodge Durango is also nice, the ones they've been making since 2011 are great looking.
With 5 seats, some German vehicles are pretty good: VW Touareg, Mercedes ML. The 7-seat Audi Q7 and Mercedes GL are still pretty expensive, although I suppose ones within that price range can be found. In terms of American ones, the Trailblazer and its cousins are good (my girlfriend has a Saab 97X, it's very nice), as are the new (2011) Explorers and Jeep Grand Cherokees.
I'm not a big fan of Japanese or Korean cars, but I suppose the Nissan Pathfinder, Honda Pilot and Toyota 4Runner aren't bad. Just not my cup of tea.
