When you look at the fastest-selling used cars, you expect to find plenty of Toyotas, Hondas, and Fords. Cars, pickups, and SUVs that are reliable, and common. Well, according to the latest data from iSeeCars, that's not the case this year. In fact, Ford didn't even make the top 10, and Toyota only qualified if you count Lexus.The car flying off the used dealer lots in the first quarter of 2026 was the recently-retired Tesla Model X. Yes, even as new EV sales are tanking, used car buyers can't get enough of the electric SUV. Meanwhile, Hyundai, Lexus, and Audi are keeping combustion power relevant. Here's what the changing used car landscape looks like today. Combustion Power Can Go Big Or Go Home In 2026 Lexus Take a look at the top 20 hottest used cars, and a few points will likely stand out.Based on this list, we can make a few quick observations. EVs make up 40% of the top 10, and 25% of the top 20. Hybrids make up 30% of the top 10, and 30% of the top 20. ICE vehicles make up 30% of the top 10, and 45% of the top 20. ICE vehicles in the top 10 tend to be performance oriented, like the twin-turbo Lexus GX 550 and the 276-horsepower Hyundai Elantra N. Electrified vehicles absolutely dominate the top half of the list, while conventional gas-powered vehicles claim the majority of the bottom half. Note that these are the hottest sellers by time spent on the lot, not necessarily by volume. That is, EVs might only make up a small percentage of used cars sold in Q1, but dealers are moving Teslas off the lot quicker than they're moving BMWs and Volkswagens. Some Of The Slowest Sellers Are Electric, Too Dodge While electrified vehicles dominate the top-10 hottest-sellers list, they also lead the slowest-sellers list, with some models taking the better half of a year to leave the dealership.Some at-a-glance observations on this list. EVs make up 40% of the 10 slowest sellers, and 25% of the 20 slowest sellers. Hybrids make up 40% of the 10 slowest sellers, and 35% of the 20 slowest sellers. ICE vehicles make up just 20% of the 10 slowest sellers, and 40% of the 20 slowest sellers. A lot of these cars are really dang expensive, even as used vehicles. High sticker prices, plus extreme niche appeal, make for some very slow sellers. Electrified vehicles are highly concentrated at both of the extreme ends of fastest and slowest selling vehicles, tapering off outside of the top and bottom 10, illustrating the high-risk/high-reward nature of the segment. It's worth noting that the Dodge Hornet is on this list three times, if you count the Alfa Romeo Tonale. A compliance car that's received relatively little marketing support from its maker, the Dodge Hornet is not without its charms, but these numbers, plus the SUV's recent cancellation, must qualify the car for some kind of loser-of-the-year award. What Makes The Tesla Model X The Perfect Used Car? Tesla We've got our theories as to why electrified vehicles in general are selling so quickly on the used market, but the Tesla Model X in particular really is the perfect used car in more ways than not.To get an idea of what makes the Model X the perfect used car, let's consider what a typical used car buyer is actually looking for. Auto Dealer Today ran a poll awhile ago asking used car buyers why they're in the market for a pre-owned vehicle, and the results are no doubt as relevant today as they were in 2011, finding the following as the leading reasons to buy a new-to-you vehicle. Previous vehicle broke down. Previous vehicle was totaled in an accident. New baby in the family. The buyer just landed a new job. There's a new driver in the family. Longer commute. Based on these answers, a used car buyer is looking for something that's safe, reliable, fuel-efficient, spacious, and affordable. The Model X fits the bill in every category.The Model X made history as the first SUV to ever score a perfect five-star rollover rating with the NHTSA. Our older readers no doubt remember when SUVs used to go on two wheels on moderate curves, but the Model X's weight distribution, with the half-ton battery pack laid out along the floor of the vehicle, helps it to keep its feet firmly planted on the road.With the Model X being an EV, you don't have to worry about five-bucks-a-gallon gas prices. It's spacious, for growing families, and Teslas are loaded with safety technology, so you won't be sweating bullets every time your teenage driver gets behind the wheel.At three-years-old, $56,200 is a steep discount off of its initial $80,000 MSRP, but, if that's still a bit high, a five-year-old model will cost less than half its original price, and depreciation flattens out to a trickle past this point, meaning that the previous owner has already seen the biggest drop in value. Electric Vehicles Just Make A Lot Of Sense On The Used Market Tesla Price has been one of the biggest hurdles in the adoption of EVs and hybrids. In the long term, you could be saving thousands of dollars on fuel and maintenance. But, when a new Tesla costs three times what you'd be spending on a new Nissan with the same number of seats, you're talking long-term savings to someone who doesn't have time to save up for a new Model X. EVs Are Attractive, But Who's Got $80,000 To Spend On A New Car? The used market ultimately levels the playing field, making long-term-value cars more available to people who need an affordable car today, so you enjoy both the up-front savings of buying a car that's already lost half its market value, and the long-term savings that come with cheap maintenance and not having to pay for gas.The value proposition helps to explain why luxury cars and potent performance models like the Lexus GX 550 make the list, as well. After taxes and a few add-ons, a GX 550 can easily become a six-figure purchase, but EVs and luxury cars both depreciate very quickly. After five years on the market, it shouldn't cost you any more than a new Hyundai. Now if only they could do something about the price of new electric vehicles.
