> “The State of Illinois has charged me because Carvana delivered a car to a customer’s home,” Breaux said in a statement provided by Carvana.

Sounds like they transferred the title but it wasn't "by a dealer", so it was illegal. In addition:

> In a separate filing on May 12, the agency charged Breaux with two counts of Carvana operating as an unlicensed used-vehicle dealer.

You can of course look up the relevant code on Illinois' wonderful online legislation document: https://www.ilga.gov/legislation/ilcs/ilcs4.asp?DocName=0625...

I had the same issue with Beepi. Had a friend who worked there -- I got the sense that complying with a bunch of interstate car sales was rather tricky and they often had issues getting through the state DMVs.
