5 cars that are better to buy when they're 1 year old

When you're buying a new car, how well it holds its value can be a prime consideration. But when buying a used car, the math is reversed. A big loss for the original owner in the car's first year can present you with a bargain -- if, of course, the car is a good one.

The automotive website iSeeCars.com has done a study to see what cars are the biggest bargains as used one-year-olds. The cars on the list, which runs heavily to luxury sedans, all delivers savings of 31 percent or more versus the new-car price for the same car's current year model.

The study reviewed 14 million used-car sales between Aug. 1, 2015, and July 31, 2016, to get the average depreciation figures. Because of the time span, in earlier cases it was 2014 models vs. new 2015s, while later it was 2015 used vs. 2016 new. The price and savings amount average all those transactions.

iSeeCars CEO Phong Ly explains that "The cars that experienced the greatest changes in price tended to be those that are less popular, especially luxury brands." Luxury models almost always decline in value faster than mainstream brands -- especially when compared with those like Honda with very strong resale values.

But recently sales of all sedans have slowed while lower gas prices have encouraged strong sales of pickups and SUVs. And indeed, the top five vehicles on the study's list of those that hold their value best -- all 8 percent or less loss in the first year -- included three pickups, a Jeep Wrangler and a Honda Fit.

We picked out five of the most interesting bargains from the iSeeCars list to tell you more about. So if you're interested in an almost-new luxury car (Volvo, Mercedes, Lincoln) or near-luxury (Buick and Chrysler) sedan, click ahead for more details.

​2015 Volvo S60

The savings on a one-year-old S60 with an average price of $27,044 is $14,204. The standard turbocharged four-cylinder engine both provides strong acceleration and is rated for 25 MPG in city driving and 37 on the highway -- exceptionally good for this class.

Test drivers also say that the S60 has a comfortable ride and crisp handling., And of course, being a Volvo, it comes with multiple safety features. The City Safety system can stop the vehicle at low speeds to avoid hitting pedestrians. And the lane keeper warns you if you're drifting out of your lane.

​2015 Mercedes-Benz C250

The only car on our list that's a two-door coupe, this sleek Benz delivers savings of $15,247 on an average price of $44,454.

Unlike some competitors, the MKS has a six-cylinder engine as standard, providing good acceleration. It's rated for 19 MPG in city driving, 28 on the highway.

​2015 Chrysler 300
