Some cars hold their value well. Reliable vehicles and models with timeless styles tend to depreciate the less. Examples include the Jeep Wrangler and Porsche 911. But other cars, especially luxury cars which are redesigned often and have expensive maintenance can depreciate rapidly.

For comparison’s sake, the average vehicle loses 38.8% of its value over five years. Here are the makes and models that depreciate the most:

So there you have it. If you bought a 2018 Maserati Quattroporte and drove it an average amount, it lost nearly $100k in value in just five years.

Depreciation happens, but it hits these makes and models harder. I posted X user “The Car Dealership Guy’s” depreciation infographic to my own feed and asked my followers what they think makes these models lose value so quickly. The responses were very interesting.

One theme was maintenance: “Expensive upkeep.” “Maintenance cost.” “Junk.” “They all have poor reliability.” “Luxury cars command a premium for repair and services, unless you are savvy enough to do a good bit yourself, to a point.”

User Nekoyama was more specific: “Obsolete parts and no market. To repair and maintain them would cost more than the estimated value.”

Another user added, “Out of warrenty repair costs.” This is a good point, owners used to having dealership service may be willing to sell their luxury cars at a loss as the five-year warranty ticks down.

Moon Man Michael had an even more intriguing theory: “I feel like part of what drives the price on these premium cars is having the latest tech, which may or may not age well. Once it’s not new anymore, a lot of the shine fades.”

Another user added, “These are all luxurious high-end cars that get renewed every few years, they lose their value as soon as they roll out of the dealership.”

One commenter wasn’t pulling any punches: “they cost too much to begin with.” Ryan specified, “Cause they are overpriced to begin with. Escalade has been like that since it was produced. Its a luxury car thing. None of em hold their value.”

It is true that luxury cars command a premium because of their badge. It makes sense that used vehicle buyers are less likely to pay that premium.

Here’s one more theory: “The types of people that buy them, tend to replace them every 3 years, so a high supply and low demand.”

All these theories are well and good. But it doesn’t explain why the Porsche 911, which is a luxury sports car that isn’t cheap to maintain, trounces everything on the above list. There may be another commonality. One user said, “Just not desirable examples of their categories.”
