I believe there is definitely masculine and feminine cars, but it really shouldn't be a factor in if you buy it or not. Z3 is feminine, the Porsche Boxster is feminine, Jag XK's are masculine, Z4's are masculine, Aston Martin's are masculine, TT's are feminine....
I think a lot of it has to do with the front of the car, aggressive = masculine.
