1990 Mercedes-Benz 560SEL Reviews

This is a great car that is reliable, the main issue to this model are the standard high-mileage leaks from the valve cover gaskets. Some dealer parts are actually cheaper than aftermarket. In comparison to the 1994 BMW 740iL, it is cheaper to maintain and eventhough it has a 5.6 litre engine, burns less fuel.
