Working on it, please be patient. The 993 Turbo Cab was a very limited production car, as far as I know production numbers didn't exceed 25 pieces. But I'm not sure if I remember it very well, I'll post some info as soon as I got it more precisely. Won't take long, I promise.
If you can put your hands on a 993 Turbo Cab, do it. It is worth the money and it is a very rare object.
