7. Hyundai Elantra
KBB private party value:
The tiny base-model Elantra didn't really change in 2003, but it's that bland consistency that keeps buyers coming back.
The Elantra's fuel economy has increased significantly since 2003, but its combined 26 miles per gallon were tough to scoff at in its prime. Its 2.0-liter engine and 135 horsepower were brawny for its class, but its roomy interior with seating for five was the biggest draw for drivers seeking something a little extra.
This year was also right around the time that Hyundai started to hit a stride in the U.S. This was five years after Hyundai launched its 10-year, 100,000-mile warranty, which is just expiring on a few fortunate Elantras. It was also a particularly good year for the company's Accent hatchback, which still holds 21.6% of its original value.
