I bought a used car the other day and I thought everything was fine until I got a text from the dealer saying the bank needs better proof of my income. I told the dealer I made X amount of dollars a month and I actually strecthed the truth a little. I know, bad, stupid move. I'm kicking myself for it now. I did have a co-signer with this car that has a really good income and I was wondering if my co-signer proves his income if that'll be enough? Thanks.
