Average Cost: $14,232

The favorite SUV under $15,000, according to iSeeCars, is the 2012 Ford Expedition. The 2012 Expedition features a much roomier third-row seat than the contemporary Chevrolet Tahoe, thanks to a space-saving independent rear suspension that lowers the cabin floor and opens up plenty of legroom (Chevy finally added an IRS for 2021). The 2012 Expedition costs, on average, $14,232.
