Try a 'global' string, if you understand what I mean.
And did you had this?:

pawn Код:

new pName[MAX_PLAYER_NAME];
GetPlayerName(playerid, pName, MAX_PLAYER_NAME);
if( !strcmp(CarInfo[newcar][cOwner], pName, false) ){ //Why the 'false'? Well, now it's case sensitive
  //do something
}
else{
 //Not owner
}

maybe something like that :')
