Purchasing a car from a private seller. Nightmare.

Hello all. With much embarassment I'm sharing my experience buying my first vintage car. Pretty much every mistake a novice car buyer can make... I made them.
First, the car. last week i bought a '67 Plymouth Barracuda convertible for $9K cash from a private seller. The guy i bought if from, Bob, owns his own body repair and restoration shop. When i arrived to look at and drive the car he had some really great cars up on lifts and in the garage. A Chevy Nomad, a Ford Falcon, a vintage Corvette. He had guys working on cars and it was pretty much a full service garage. Lots of cars out in the parking lot too.
My wife and I met Bob and she and I took the car for a test drive. All seemed fine for the most part. Keep in mind that my Dad did teach me that when you buy a used car from a private seller you should have a trusted mechanic check it out for you. I knew that but the guy selling it appeared to know what he was doing. He had a business and surely he wouldn't screw me over, right?
I went ahead and purchased the car and he delivered to my house the next day, Saturday. He even brought his wife Mary and invited me and my wife to a car show that was coming up in a few months. I then took the car for a drive and noticed that the front left wheel was leaning in from the top when i made a left turn, so much so that i had my wife take a pic of it. I sent it to Bob so that he could see it. No response but he was going in for hip surgery the following Monday.
I thought it might be a tie rod or a ball joint or something. Hey, i did expect to have some repair work done on it, i'm not completely insane. I took the car to my mechanic and he checked it out. Basically there is a crappy repair weld by the front wheel that is vrtually impossible to fix without straghtening the frame which could then compromise the frame given the age of the car... then the dominos fall and next thing you know i'm spending thousands more dollars to work on the frame.
I found out too that shops won't repair the weld as it's too much of a liability. A custom car shop is looking at the car later this month to give me the verdict but it doesnt look good. The other piece of this is the title. Bob gave me the title and it had another person's name on it. His name was nowhere to be found. I thought it was strange but I went ahead with it. Come to find out there is this thing called title skipping. The car could be a salvaged car or a stolen car! Could this get any worse?!
I sent an email this morning to him and texted him to tell him he has an email coming his way. I didn't threaten legal action (I know, buyer beware and there probably is very little i can do about it) but he did text me back to say call him. I basically explained the issues and said i expect that we can connect and get this thing straightened out.
The whole thing is extremely embarassing and i know it could be much worse. Any suggestions or recommendations on what options i have? Of course i'm investigating but from everything I've read there isn't a lot to do but see if i can reason with the seller.
I appreciate any advice someone may have and i fully expect to get made fun of as well. Thanks in advance and i'll keep you posted on the latest developments.
