This is a map of all vehicle spawn locations in GTA: Vice City. Mouse over the yellow arrows for more information on the spawn point. Information includes:
Car model name
Color if applicable
Force spawn if applicable
Alarm if applicable
Door lock if applicable
One thing to note is that not all vehicles on the map actually spawn. The PCJ 600 at Prawn Island and the Pizza Boy at Star Island are placed too low into the ground, preventing those vehicles from spawning at all.
