If i put $4000 down for a car how much will the payments be?
07 Mustang should be in the low teens, unless you are looking at a GT, which would be way more. Let's pick a price, say, $12K. With taxes and fees, the total will be closer to $13.5K. Apply your $4K down, and you will finance about $9.5K
With good credit, for six years, your payment will be about $17 per thousand financed, or about $162. But most lenders want a shorter term on a loan this size, so you'll be about $20 per thousand for five years, or $190. If your credit is only so-so, the payments will be higher, because the interest rate will be higher. If it is poor, you will have no payment at all, as credit is tight right now.
Does this help?
