Typically, people think of pickup trucks as a solid buy. Like all motor vehicles outside of the occasional ultra-collectible exotic, trucks lose value over time. But compared to a lot of those vehicles, pickup trucks have a history of holding their value pretty well.

If you buy a Toyota Tacoma, that advice holds true. Over the next five years, expect a Tacoma to lose less than a third of its original value. But there are some trucks that hold their value worse than others. According to iSeeCars’ latest report, these five trucks have the worst depreciation.

Chevrolet Colorado

This is a bit of an unexpected one because in addition to being a solid truck that’s gotten great reviews in the past, the Chevrolet Colorado’s mechanical twin, the GMC Canyon, has a significantly better predicted resale value. Maybe that Denali trim really is worth the higher price tag.

Still, the Colorado is no BMW 7 Series. It may be on this list, but considering the 7 Series loses 72.6% of its value over five years, the Colorado’s 46.0% depreciation looks pretty good. Unfortunately for Colorado buyers, there are several trucks that would depreciate less quickly.

GMC Sierra 1500

The way this list starts off, you may think iSeeCars was picking on General Motors when it published its report. Having seen the rest of the list, though, we’re confident that’s not the case. Especially since, as we just mentioned, the GMC Canyon beats the Chevy Colorado on resale value. In this case the Silverado beats the Sierra.

Interestingly, the Sierra and the Colorado are basically tied here. While the Colorado should lose 46.0% of its value over five years, the Sierra 1500 is only slightly worse, clocking in at 46.1%. Slightly wore is still worse, though.

Nissan Titan

Out of all the trucks on this list, the Titan surprised us the least. In fact, we would have actually guessed it had the worst resale value for any truck on the market. And that’s why we’re writers, not gamblers.

Still, it makes sense that the Titan wouldn’t have great resale value. The reviews haven’t been kind to the Titan since it was redesigned, and lately, Nissan has fallen behind when it comes to in-vehicle technology. Over five years, the Titan should also lose about 46.9% of its value.

Ford F-150

While the Nissan Titan has slightly better resale value than we would have thought, it’s the other way around with the Ford F-150. We would have thought the F-150’s depreciation would be lower than it is. So again, we should probably stay away from the tables in Vegas.

Maybe Ford just sells too many of them new. Or maybe it redesigns the F-150 too often. But whatever the reason is, iSeeCars has the Ford almost at the bottom of its truck resale list, losing 47.3% over five years.

Ram 1500

Maybe the upcoming Ram 1500 TRX will do something to improve the 1500’s resale value. Maybe not. But at least for now, the Ram 1500 has the worst predicted resale value on iSeeCars’ list of trucks. If you buy a new Ram 1500, expect it to lose 49.3% of its value over the next five years.

As we’ve mentioned before, though, resale value and cost of ownership don’t necessarily correlate. So especially in the case of the Ram, poor resale value means you can probably get a great deal on a gently used model. Definitely make sure you get a pre-purchase inspection, but if that comes back clear, don’t be afraid to pull the trigger on a used truck.
