• Used-car prices are at record highs, and prices on some models are spiking.
• CNN analyzed Edmunds.com data to compare new retail prices in 2020 with used retail prices in 2021.
• The Corvette saw the biggest gain of nearly $26,000, due in part to fewer new ones being made.

Normally, a car loses as much as a quarter of its value in its first year, but a CNN analysis of Edmunds.com data found that a few models have actually increased in value since leaving dealers' lots.

Here are nine models that have gained the most value in the past year.
