Bought a lemon

Just bought a van (Feb. 13, 2014) and was told only needed a strut mount. Took it in and mechanic said needed new struts and bushing. Ok, bought it cause guy dropped it down $500 - basically the cost of the repair. So as I am driving home with the car it starts making a weird whining sound. I call a guy and take it in immediately - he says it is the power steering - they over filled the reserve, which means something is wrong with the power steering - says it will cost at least $150 to fix. I call S&S and he acts like he has no idea what I am talking about, when I say power steering was overfilled again he has no idea and claims he didn't do it. Not true! Refusing to do anything. He knew we were buying with income tax money and we have 6 small children. He sold a death trap. NEVER BUY FROM THIS GUY - WILL RIP YOU OFF ANYWAY HE CAN! had to give 1 star or wouldn't let me post.
