I work in Newton.
I'm from Rockdale and I've seen the black stock TT one, a skinny white guy drives.
I saw it on the ramp coming off I20 about a year ago in Covington. I've seen him from time to time throughout the year also. He replied here one time when I posted about the sighting a year or so ago.
I also saw a Teal colored one parked in front of the shopping center where the MRI scanning center is in Covington. Seen it in Rockdale also a couple of times.
Never scene your red one though or the other black one you described.
Also see a white stock TT in Conyers from time to time a black female drives.
