I live in Longview, Texas and have seen (3) STS V's besides mine. One silver with black wheels, one silver with chrome wheels, and one black with factory wheels. Two were driven by women. I own a gray(looks bluish) with Gibson exhaust. Can't figure out why so many in a small town.
Sounds like there are a few of us Dallas guys here. I am in Coppell and have only ever seen 1 or 2 other STS V's around. Mine is a Silver with Silver wheels version that seems to have a cop magnet on it.
