When the 560SEL was built, it was the flagship of the Mercedes-Benz lineup. This was before Lexus. MB engineers were given a blank slate (literally) to create the 560SEL. All costs were passed to the buyers, who in 1990 were throwing down about $80k. But that was 1990. What's it like today? I'm a car nut and I love this car. It has character and it gives meaning to the word 'quality'. If you take care of this car as you're supposed to, it can last forever and actually be a good investment (really). If you're in the market for this car, the gas mileage should be no surprise. It's really bad.
