I'm looking at a 2015 389 pete with 230K on it for 99K. Putting 10k down it's working out to be 1,825.00 for 60mo @ 9%. I have 1 yr with my own authority with a fico of 770. Buying a truck or any vehicle always do it in three stages 1. Price 2. financing 3. Trade in. Never mix the three ever !!!! you will lose ever time. Always know the price before talking financing or trade value. They will want to play the three card Monty game of mixing the three don't fall for it. What I mean is make them earn your business their are 1000s of trucks for sale, 100s of financial institutions loaning money. Remember 80% of wholesale is what the financial institutions will want to loan on a used truck. So if they is asking full retail price or higher for the truck your down payment will need to bring the price close to 80% wholesale. This is where your credit and income come into effect.
