1989 Mercedes-Benz S-Class 300 SEL 3.0
Other 20 year old cars can't even come close to it
Really nothing has gone wrong with the car, just sometimes when you start the car, it will idle roughly until warmed up, then it will run properly.
The car needs a brake master cylinder, as the brakes are mushy.
The A/C condenser needs to be replaced as well as the seals, but hey, 20 years, it's about time for it.
Otherwise, it could use a full service and tune up.
I will say that they don't build Mercedes Benz cars like this any more. The car is clearly over engineered, and the materials are of the highest quality. Most Japanese luxury cars from this era did not age well, this car has fit and finish that are just not seen anymore.
The inline 6 cyl engine is a bread and butter engine for Mercedes, and gets excellent MPG and give you all the power you need on the highway for a big body Benz. To me, the 560 SEL is just overkill.
It's rock solid on the highway; it's a car you want to take on a long trip and no other 1989 car can touch it in terms of aging well, performance and 5 star safety
Would you buy another car from this manufacturer? Yes

I agree with you, the 560SEL is overkill, a gas guzzler, and also the 560SEL has issues with the rear hydraulic suspension where it will go out and cause rough rides, and the car to sag in the rear.
Also the 560SEL is notorious for the timing chain going out and that includes the 420SEL.
The 300SE and 300SEL have the best straight six in them, and low on maintenance with good gas mileage.
I own a 1989 300SE, and they are the best and will last longer than the 420SEL and 560SEL V-8 engines. Just follow the recommended routine service by changing the spark plugs, air filter, fuel filter, and other services.
