Draper Auto Sold a lemon and refused to repair a week after buying. Draper Utah

We bought a Sprinter van from Gary and it immediately had problems after buying it (a week after) that he has been unwilling to do anything about. After water poured in from the ceiling because of a bad seal on the AC unit he said to bring it buy to look at it and then ignored us when we emailed back to ask a good time. Before buying he said to not worry about a battery light, it came up to be a $400 alternator repair. He said to not worry about the check engine light, it turned out to be $4,000 engine repair. When the radio wasn't working but the listing said it did, we even offered to split the cost of his bid of $400 and then settled to pay 300 of it only to find the radio he put in was a $80 after-market one. There were other issues too but not enough space to mention them...Before we finalized buying it he offered us a $3000 warranty for it, something we couldn't afford so he assured us that "I take care of my customers". I recognize I have no legal recourse as we signed for an as is vehicle. But over $6000 of repairs only a month into ownership and he has declined the opportunity to take care of us in way. The only offer was to quote our repairs with the shop he uses, in theory to get us a "wholesale deal" on the work. When we asked to send us a quote we got nothing and nothing since. Gary is nice in person but is not a man of his word apparently which is sad that this happens still. His son who works with him however, was rude whenever we worked with him. I don't even remember his name as he didn't even introduce himself when I went in to buy the car. If you are looking to pay a little more for the quality cars they claim to sell I suggest buyer beware...
