Mercedes-Benz SLS AMG - red - at speed in a forest

Picking up a used luxury car is a great way to save some coin. Letting the previous owner take the fall on depreciation is a smart move, but it's worth remembering that high-end autos carry with them high-end maintenance and repair costs. Using Edmunds.com data, 24/7 Wall Street has compiled what it says are the 10 most expensive vehicles to own, and the list is populated by some not-so-surprising names. BMW and Mercedes-Benz soak up the lion's share of the offenders, though other manufactures make a showing as well. Perhaps not surprisingly, the Mercedes-Benz SLS AMG takes top honors as the most expensive of them all with a "true cost of ownership" of $245,469. That's in addition to the gullwing supercar's $210,875 MSRP.

The calculations not only factor in deprecation, but also things like fuel, maintenance and insurance costs.

All told, Mercedes-Benz models takes four of the 10 spots on the list. That's twice as many as BMW, and the rest are split between makes like Land Rover, Audi and Nissan. If that last one seems a bit out of place, keep in mind Nissan makes the mighty (and mighty complex) GT-R. Check out our gallery below for a full list of the biggest offenders.
