2001 Mercedes-Benz S-Class S500 4dr Sedan (5.0L 8cyl 5A)
I absolutely loved this car. It was fully loaded. From the voice command system, to the doors that automatically close themselves I loved it. This car was great. But in the 5 months I owned it I went into the dealership about once a month and each time cost me $500 and over. Until we had a torrential rain and water seeped into the car through the water box and destroyed all electronic components located under the seat. I'm torn because I don't know whether that the faulty water box was the source of all my service trips or shoddy reliability.
All the hi tech features. And the drive. This car was silky smooth and ultra fast..
Build quality. I took this car in once a month until the whole things just gave in on me.
