I have an e90 SSII with stock 19s. I live near 168th and Pacific so it could have been me you saw. I know of a few E9x M3s in town. A black coupe, a grey coupe (with winters on it) and a white coupe. I was told there is another SSII sedan in town like mine, but i have not seen it. I have also seen a red e90 in Lincoln. Markel just delivered a red e90 to a woman in Sioux City.
