Pre-approved Capital One Auto Loan. He sent a letter w / distributor?? Legit?
They sent me a letter from Capital One saying I'm approved for up to one autoload 30K. I was given the name of a local participating dealer to go to between 28 and 30. I called the number to confirm the pre-approval number capital and it is something automatic number one. The numbers 18006859508 and approval number is 451,320,233. It says I can walk in there with no money down and owner A car that day of Deal Maker Ford in Liverpool NY. All I have to do is bring proof of income and a utility bill, along with my driver's license and insurance to drive a new house. This is almost good to be true. My credit score is only 600 to mid-way I never thought I qualify for something like this. I've been a customer of Capital One for 2 years with a limit thats credit card $ 500 in good condition.
Auto finance is what I do for a living and that's a valid offer. The dealer is making a sale of equity, I have made these several times and Cap-1 sends the cards and is approved. The last I did I had people drive over 350 miles to buy a car because local merchants could not get approval.
