First, the Doge Charger SRT8 is more than 32,000. I paid 47,000 for mine back in May. 9,000 is enough for a down payment. The next thing you have to think about is how long you want to finance the car for. You can finance a car now for up to 60 months. Say the Charger is 32,000 and you put 9,000 down, that leaves a balance of 23,000. So for the payment per month would be 23,000 divided by 60, the amount ot this number would be your payment per month. I hope this helps. Good luck!
