pawn Код:

new carownerrr[MAX_PLAYERS];
  carownerrr[getplayerid] = PlayerInfo[vehicleid][pCarKey]; // I guess here is the problem, as i added "vehicleid" it should really say "playerid"
  SendClientMessage (DynamicCars[carownerrr][getplayerid][cOwner], COLOR_RED, "Your car got destroyed.");

im not sure thoґ if it helps, but you can give it a try
