Americans tend to want all the “bells and whistles” on their new cars. Today’s shoppers are opting for higher trim levels and costlier option packages, an Edmunds’ analysis shows.

These upgrades now add more than $10,000 to the base price on average, an increase from closer to $6,500 a decade ago. Even accounting for inflation, this is a significant upward trend.

Naturally, fancy add-ons make new cars more appealing. But the data show they don’t hold their value over time, which creates an opportunity for the used-car shopper to get more car for the money.

Take the 2016 Lincoln Navigator, for example. If you were looking for the base 2WD Select model and the top L Reserve trim now in the used market, the price gap between trims is $7,329. When they were new, the price difference between the trims was $13,455.

That’s not to say Edmunds recommends the top trims for everyone. Simpler is sometimes better. But steeper depreciation makes the jump up in trims less expensive, giving you more options when shopping for a used vehicle.

We should note that while upper trims will continue to depreciate over time, the prices will eventually plateau. In the meantime, opting for a higher trim level will often give you access to better safety features, leather seating, a stronger engine, an upgraded infotainment interface and more.

Also, some extras can actually help retain value down the road. Ivan Drury, senior manager of insights for Edmunds, says traditional upgrades such as engine options or all-wheel drive in place of front- or rear-wheel drive will command a premium in the used market. These are things to keep an eye out for when shopping since there will always be a demand for them.

Vehicles to consider

We’ve selected a few vehicles that illustrate the price difference between trim levels in the used-car market, sorted from the smallest to the biggest price difference. Many of these are among Edmunds’ top-rated used cars.
