Everybody i need your advice i just saw a 91 300ce there asking for $17,000 and the mileage is 69k miles,it doesnt have a service record.The inside and outside of the car is flawless,immaculate .I drove the car the ride was smooth and the engine is quite.The only thing that bother me is when i open the hood i saw a the headers has alot of rust and below the headers i saw a leakage of oil even the undercover of the engine has a trace of oil.Probably its the head gasket problem huh. Do you guys think it worth buying this car.thank you
