You can get a pretty sweet Dodge Durango or just about any comprable 2000 SUV for about 18K.
You're gonna get killed on the depreciation the minute you take a new American car off the showroom floor.
Think about perhaps a used (~3 years) 3 or 5 series BMW or the GS 300 Lexus; these are beautiful, quick, excellent cars that generally still look new at 30,000 miles and will run forever, are relatively straightforward to maintain, many have extended 100,000 mile warranties, will not break the bank, and depreciate very slowly. Check out eBay to get an idea of what you should be paying.
