Body problems of the 2007 Mercedes Benz S550

I brought a car from a car dealer in tampa florida and when I got the car I noticed that the car would not pickup speed after pressing the gas pedal and it was asking me to turn off the engine or it will fail . Also when I tried to put in coolant. I seen a milky substance that was coming out of the hoses and in the overflow tank of the coolant reservoir which indicates issues with the heads or head gasket . Also the title I got says salvaged which I asked if there was anything wrong with the car and the car dealer told me no . Never disclosing that the car has been salvaged . There are other issues with the car that I forget because of so many issues with the car that I cant keep up with and I want to return the car to the car dealer and get my money back and have tried but they refuse to make good on the sale.
