Since the responses show functions instead of the vehicle spawn, my guess would be take a look at Dialog_CarOption(playerid, response, listitem) and look for CreateVehicle. If it's not assigned to a variable, assign it to one, ex:

pawn Код:

new vehicleid = CreateVehicle(modelid, Float:x, Float:y, Float:z, Float:angle, color1, color2, respawn_delay);

Then you can set the vehicle's virtual world with the variable.

Also in the future place your code in [PAWN] tags, makes things easier to read.
