You are describing the "Special Edition" roadster. I bought mine this summer (my third roadster but first SE/Base).

The SE is a Base Roadster with those wheels, red paint, and an optional automatic transmission. The SE is, I do believe, the rarest sub-model of Crossfire. Because it's numbers are buried in the "Base" numbers, the actual number of these cars built is not known. Out of 56 cars set to go to this weekend's Dragon event, two will be SE's. For the SE, I believe that is a record Dragon attendance.
