you need to store that in variables.

pawn Код:

new vehiclelevel[MAX_PLAYERS]; //global variable

pawn Код:

vehiclelevel[playerid] = 0; //onplayerconnect

if you have that command which gives vehicle owner rights to a player .
add these lines to it

pawn Код:

if(vehiclelevel[playerid] == 0) vehiclevel[playerid] = 1, SendClientMessage(playerid, color, "you owned 1st vehicle");
else
if(vehiclelevel[playerid] == 1) vehiclelevel[playerid] = 2, SendClientMessage(playerid, color, "you owned 2nd vehicle.");
else
if(vehiclelevel[playerid] == 2) vehiclelevel[playerid] = 3, SendClientMessage(playerid, color, "you owned 3rd vehicle");
else
if(vehiclelevel[playerid] == 3) return SendClientMessage(playerid, color, "You cant own any more vehicles as you already owned 3 vehicles.");

pawn Код:

vehiclelevel[playerid] = 0; //onplayerdisconnect
