I know little about KMX operations, but we often bumped up against their buyers at the auction. I dreaded when they were interested in the same vehicle I wanted, because they would bid up the car to what I felt was a ridiculous number in order to get it. We were a small volume operation and needed to buy vehicles at a decent value in order to make good grosses, but they didn’t seem to care what they bought it for as long as they bought it.
This was a few years ago before used vehicle prices shot up to ridiculous heights. If KMX was able to navigate the recent used vehicle shortage and price increases fairly painlessly, it seems like they definitely have a model that works.
