Is it illegal to sell a salvage title vehicle to a buyer without giving them that information?

I purchased a vehicle from my ex boss/friend. The vehicle was a 2013 Acura TSX, it had about 70,000 miles on it for $8500. I had bad credit and I could not get it financed to anyone but him. I started having issues with the vehicle going through tires, the front tires would go out within a day of each other. I have gone through 3 sets of tires, last time I had to leave My car at a gas station and it was towed because my flat happened at night in the middle of the night. The next day when I went to the gas station it was towed. I didn’t have the money to get a wrecker. I was really low on cash at the time and I had it in the storage lot for almost a week but I was working on it and finally got the money to get it out and to get the tire fixed because that’s what it was going to take. But when I called my car was gone my boss her ex friend boss had picked up the car from storage lot. A few days earlier I confronted him about the title, he said he would get back with me, he didn’t. Help!!
