15 cars gaining the most value on the used market right now

Second place is the Volvo S90, which increased by 16.3 percent, or $5,164, to $36,934. Again, I’ve felt that Volvo cars have been pretty undervalued on the used market up until now, so it doesn’t feel too egregious for the average price of a used S90 to jump up this much. It’s a great car, and that’s still a pretty reasonable price for what you get.
