You know the script for buying private vehicles. For example: In the living room there is an Elegy car and I get in this car and show Dialog. Buy or cancel.

PHP код:

// define dialogs first
public OnPlayerStateChange(playerid, newstate, oldstate){
    if(newstate == PLAYER_STATE_DRIVER){ // You need to add another check here so this will be called only in showrooms
        new string[128], price, carid, modelid;
        carid = GetPlayerVehicleID(playerid); // Get the vehicle id for future use
        SetVehicleParamsEx(carid, 0, 1, 0, 0, 0, 0, 0); // ENGINE OFF or player will run away with the car lol
        modelid = GetVehicleModel(carid); // Model id, Elegy is 562
        switch(modelid){
            case 562:
            {
                price = 12500;
                format(string, sizeof string, "Elegy1n Price: $%d", price);
                ShowPlayerDialog(playerid, DIALOG_CAR_BUY, DIALOG_STYLE_MSGBOX, "Buy a car", string, "Buy", "Cancel");
            }
        }
    }
    return 1;
 }   
 public OnDialogResponse(playerid, dialogid, response, listitem, inputtext[]){
    switch(dialogid){
        case DIALOG_CAR_BUY:
        {
            if(response){
                if(GetPlayerMoney(playerid) < 12500)return ShowPlayerDialog(playerid, DIALOG_NO_MONEY, DIALOG_STYLE_MSGBOX, "Buy a car", "You need 12500$ to buy a Elegy!", "Ok", "");
                // Take money from player, save player data adding car property etc
                return 1;
            }
        }
    }
    return 1;
 } 


Of course this isn't a solution, is simply to give you an idea.
