<prompt> Human: So long story short, my SO works at a fast food place and is trying to get on his feet with no credit. Hes 24 and got his license 2 years ago. Im 20 and have excellent credit and a great paying job for someone my age in our area. He has been turned down because of his income which is 10hr, well above min wage. We tried JD Byrider and a few other local buy-here-pay-here places. We want to buy from a lot so we can be sure we dont get another lemon like his current vehicle. We went to a local lot and the salesman said oh yeah your girlfriend can cosign so you can get approved for a nicer truck. So he runs my credit and says yes, we can get the truck my SO wants. So we went home to try and get insurance quotes also note that he doesnt have insurance because it is insanely expensive and we finally found a decent quote.We went back to the lot and the salesman said great, we will submit the forms and just call back tomorrow morning and we can go from there. Well I had to work the next morning so my SO goes by himself, down-payment and insurance quote in-hand. The salesman said he has to take me off the loan because he would be losing money. I assume because I qualify for a lower interest rate. Anyone have suggestions or similar experience?Edit: ok so you guys have talked me out of co-signing. Anyone have suggestions for him to get a vehicle? He has 1500 cash to put towards a down payment or a cash purchase. Like Ive mentioned below, his car now is on its last leg. Walkingbusbiking are not options because he lives in a rural area and the highway is the only way to get to his job. Given the situation, would it be best to try for something on Craigslist, or try a brand dealership, or even a credit union?  <response>: Plot twistThe salesman is a regular on rpersonalfinance and is trying to save you from making a huge mistake.
