It generally is, but that could be the difference between owning one and running a fleet. They are low maintenance and rarely require repairs, but when they do, they can be awfully costly. That could result in a low median cost but higher mean cost. Owning 20k means you are going to have to deal with that average, but an individual owner probably lucks out with the median cost.
Can confirm. For a fleet owner, cost to repair vehicle is generally modeled as an [1] exponentially distributed rv, which has a positive skew, so [2] mean > median.
