Where I live in Houston which is near downtown and Memorial area, I'd say I see at least 3 to 4 on daily basis. In my neighborhood I know for a fact there are at least 6 to 7 including 993s too. Mind you there ar only 1 or 2 turbos the rest are 996s and Boxsters but there are quite a bit.
There are several TT's in my neck of town. Arena red, seal grey, white, black, blue and artic. There is a guy locally that drives a McClaren as his daily driver.....must be nice!
