Don't recall ever saying couple. And even if I did, why does that have to mean they are married? It's her. She has a kid. Her BF has two of his own and works full time. She stays at home with the kids.
There is alot of grasping and assumptions about details that don't matter the slightest. Her life story has nothing to do with any of this.
I gotta wonder though, if she was 35, married, and both had good paying jobs, would anyones opinion on how the dealer is handling this be changed?
Our lives are determined by the choices we make (added If you're atheist, perhaps a sprinkle of good and dumb luck, and for others perhaps by the grace of God).
I've bought nothing but used cars since my first VW in the 80's. The first car I did have to have my parents co sign for it, and they ran me through the routine as far as getting everything in writing as well as having the car checked out within the warranty period by a second party (added to see if you can contact the original owner, as back then you didn't have other means to check a vin number LOL). The next couple of cars I didn't need their signature anymore, but I went to them on advice / feedback on what to look for. Now I just go in with cash in hand and look for the best deal vs value. Last car we bought we drove 3 hours into Virginia to pick up at a dealership we found online for our "family car" (Honda Pilot, older model with 65k on it when we bought it, for less than 15k). No problems as of yet other than standard maintenance after putting 80k on it.
Could the dealership of handled this differently for your cousin? Sure could of. Would I go back there if I was the buyer in the same situation? No way I'd go back (I wouldn't of put myself in that position to begin with).
That said, the dealer is NOT a crook given the circumstances. A USED vehicle was bought with a warranty. That warranty expired and a problem was found out AFTER the warranty expired. Again, could the dealership of handled it differently? Yes. But they didn't. They (dealership) may not understand the concept of customer service and trying to earn business, but again, they are not a crook. Should the dealer stand behind their service work? Yes, however, what was bought was a used with a written warranty.
If I buy a used car and the dealer said they did service on the vehicle, I don't really care, I'm still having someone I trust check out the car. This is a basic used car buying practice that covers the buyers back. Your cousin by not trying to protect her LARGE investment, through her own lack of actions, did contribute to this situation. This is what you call a learning experience. Since her own parents or boyfriend apparently didn't understand this concept of buying a used car, perhaps she will learn from it.
I do sincerely hope things work out for her in her favor, but I wouldn't bank on it.
