Gta:3 & VC ive always used the D-Pad but For SA i use the Left Analog. I've now found out that the D-pad tends to be more sensitive so i don't use it anymore.
My favourite "Pimp" car would have to be the Remington but my favourite fast car would be the Turismo. My favourite plane is the Hydra. Theres lots of cool vehicles though, I just take whatevers available.
