general problems of the 2002 Lexus ES

I bought this car from all auto sales. The same day, less than an hour later I attempted to drive the car home and it broke down in front of a red light. The salesman reassured me that nothing was wrong with it. I tried to start it back up and it wouldn't start so I had to push it to the side of the road, while pregnant and two kids present. It was sold to me "as is" and I have no temp tags and I'm expected to pay a bi weekly car note. I had to payout of pocket for a tow truck and at this point I just want my money back it's only been two days and I'm already experiencing problems out of this vehicle. Please help.

I just purchased this car (Lexus Es 300 2002 sedan) for my daughter less than a week ago on 4/11/2014 from a private owner, with 267,000 miles and it ran well for a transportation vehicle, seems to have been well cared for mechanically, interior and exterior is in great shape and was checked out my friend a longtime mechanic. My daughter had just left the dmv which was closed today 4/18/2014 and street driving back home. The car made a loud popping sound, smoke started from under the hood and soon flames and she had to pull over and ditch the car. Soon it blazed and the whole front end, engine, windshield the front tires all burned. Fire and police departments showed up, extinguished the fire and did traffic control. The fire damage was control to the front and engine, the firewall did it's job. All the interiors, dash and console are all in tact and in good condition no smoke damage.
