Jalopnik reader Kyle Lackey found a parking lot with a pair of ATS prototypes and a covered CTS on his way to get some breakfast in Denver. He came back that night and found a number of covered GM prototypes, including this covered wagon.
Cadillac will not comment on any of these pictures, but it's possible that we're looking at a CTS wagon, given that it's next to what appears to be a CTS sedan. That car has the same rims as the CTS prototype Car and Driver showed off.
ATS or CTS, this wagon has us drooling. A distinctive American longroof is always welcome in the Jalopnik offices.
Kyle also saw that CTS prototype that morning and gives a better look at its Ciel-esque front end. We straight-up love the Ciel, so this is a good thing.
