um the warring was from how you used SendClientMessage

it expects 3 arguments and you where passing 4

your code

pawn Code:

//                1        2            3                                 4
SendClientMessage(playerid, -1, "%s has given you a vehicle", GetPlayerName(playerid));

my code

pawn Code:

//                 1        2    3                                
SendClientMessage(playerid, -1, str);

so you should not have any warnings with the code i posted above.
