There's an old saying to the effect that when someone with money meets someone with experience, the usual result is the the person with money gains experience and the person with experience gains money.A young female friend of mine just got herself into a predatory loan on a 2017 Jeep Patriot. She has no credit history and doesn't really have a concept of financing or banking. Unfortunately, she decided to replace her aging Explorer with a brand new vehicle rather than consulting with anyone about what the best course of action was. She went down to the Jeep dealer and signed her life away on what is one of the worst loans I've ever seen. $600/month for 72 months at 27% APR. She's going to end up paying $43,000 for that turd if they don't repossess it first. She's also going to be so upside-down that she'll never be able to get rid of it. It's frustrating.
Oh - to add insult to injury, they talked her into a $2,200 maintenance plan that covers oil changes and tire rotations for 2 years or 24,000 miles.
Check the consumer laws in your state. Ohio has a three-day "cooling off" period on new car purchases during which the deal can be unwound. It's possible that some other states have similar laws.
