Bad Car Deal

oldschool350z

So my dad recently purchased a vehicle for my brother.

It's a 2008 Dodge Magnum with 82k. They grossly over paid (I told them not to purchase because of many reasons). They owe $11,400 to the finance company. The problem is the vehicle gold with an open recall in the ignition has issues causing the car not start. There is no permanent solution or fix. My father was unable to go to the hospital due to this issue.

the car was purchased less than 30 days ago and the dealer will not simply take it back. the dealer will allow us to find a different vehicle on their lot and then pay full price no negotiation. They will give trade in value of $10,500. I know they are playing a numbers game at this point. I went to other dealers and it's what I've thought the vehicle is only worth $7,000 or so.

What are my other options? The salesperson was not only rude but seriously a ****. They are very shady because they will go to the hospital for my dad to sign papers.

Oh and the kicker is the interest rate for the loan was 7.25%.
