OK folks, here's one I stumbled across with a short suspense. 2013 Caprice with a 3.6, 66K miles being auctioned Monday, 3/13 at an auction house in PA. Sounds like a good grocery-getter, there's only one pic but I think it's a 9C1 based on the fact it's got a spotlight and the 9C1 wheel covers. This is the location...
CARRIAGE TRADE PUBLIC AUTO AUCTION
1575 Alan Wood Road
Conshohocken , PA - 19428
And, here's the linky to the car from the GSA website; https://autoauctions.gsa.gov/GSAAutoAuctions/VehicleDetails/6G1MK5U37DL807791
