// First you should probably change it to return the message instead of continue, as even if one statement turns false it will continue to execute the next if statement.

CMD:repair(playerid, params[])
{
    if(!IsPlayerAdmin(playerid)) return SendClientMessage(playerid, -1, "SERVER:Unknown Command.");
    if(!IsPlayerInAnyVehicle(playerid)) return SendClientMessage(playerid, -1, "ERROR: You're not in a vehicle.");
    
    RepairVehicle(GetPlayerVehicleID(playerid));
    return 1;
}

Hope this helps.
