Java : Warum wartet der Scanner nicht auf meine Eingabe?

Hallo,

Gebt mal folgenden Code bei euch ein und startet : 

package Lernen;

import java.util.Arrays;
import java.util.Scanner;

public class CarSeller {

    int rColor = (int)(Math.random()*9);
    int color;
    int ps;
    int mark;
    String color2;
    String ps2;
    String mark2;
    String[] colorArray = new String[10];

    public void price(int color, int ps, int mark) {
        this.color = color;
        this.ps = ps;
        this.mark = mark;
    }

    public int RandomColor() {
        System.out.println(colorArray[rColor]);
        return 1;
    }

    public static void main(String[] args) {
        CarSeller acess = new CarSeller();
        acess.colorArray[0] = "Black";
        acess.colorArray[1] = "Green";
        acess.colorArray[2] = "Red";
        acess.colorArray[3] = "Orange";
        acess.colorArray[4] = "Blue";
        acess.colorArray[5] = "Cyan";
        acess.colorArray[6] = "White";
        acess.colorArray[7] = "Brown";
        acess.colorArray[8] = "Yellow";
        acess.colorArray[9] = "Grey";

        System.out.println("Hey, what do you want to do ? | BUYCAR | DRIVE | GOINHOUSE | BUYPLOTS | REFUEL | QUIT |");
        Scanner start = new Scanner(System.in);

        if (start.equals("BUYCAR")) {
            System.out.println("What car do you want to buy? | Lamborghini | Porsche | VW | Mercedes | BMW  | Tesla | CANCEL|");
            Scanner a = new Scanner(System.in);
            
            if (a.equals("Lamborghini")) {
                
                  CarSeller Lamborghini = new CarSeller();
                  System.out.println("Which color do you want ? | Choose one ");
                  System.out.println(Arrays.toString(acess.colorArray));
                  System.out.println("Or do you want a random color ? | Random");
                  Scanner colorchoose = new Scanner(System.in);
                  
                  if (colorchoose.equals("Random")) {
                      System.out.println(acess.RandomColor());
                  }


            }

        }
    }

}

Bei mir wartet der irgendwie nicht auf eine Eingabe... Wie behebe ich diesen Fehler ?
