fastz28,
If you can get a good price, and if you don't mind having the "old" body style once the new ones come out next model year, definitely consider it. Comments from the peanut gallary aside, in reality my unscientific observations indicate that Z3 drivers are probably split 50/50 male/female. The only conclusion you can draw from that is that as many men as women enjoy tooling around in a very fun, well-handling roadster. I found that September/October is a good time to shop for Bimmers because it's the end of the model year for many of their cars. 6 months ago my dealer called me to ask if I was interested in an M Roaster, M Coupe, or 740i all priced well below invoice.
FWIW, you should check out an autocross event sometime, where you'll likely see plenty of people driving "girlie cars" spanking wannabe's who show up in their 300+ HP monsters but can't drive worth a darn
