I owned a W220 S500 for 15 years and was satisfied with everything, but I was disappointed with the rough 8-cylinder engine and the sluggish, sluggish response of the Airmaticus, so I switched to the S600. ​@ Differences between S600 and S500: Although it is the manufacturer's highest-end car, it is a car that does not just pursue comfort as expected from a German-made car. It is more comfortable than the S500, but is incomparably sportier than the S500. The engine texture is much smoother, but the engine sound and acceleration feel are incomparable. Of course, the engine power is more than enough. It accelerates uphill on the Baekdudaegan mountain pass just as it accelerates downhill. I dare say that the ABC suspension is a magical suspension that allows you to comfortably corner while your family is asleep without having to operate the brakes, even on the Hangyeryeong Pass. On the other hand, when driving roughly, I think it is the strongest suspension in existence that allows the long wheelbase S-Class to maneuver like a compact car. @ Advantage: The ABC repair is complete and the generator repair is complete. ​ - The car was 20 years old, so of course the ABC system had to be repaired. ABC system repairs were properly completed with a mechanic with extensive ABC experience, and the generator was also replaced with genuine parts. - I think the advantage of this car is that no unnecessary tuning or maintenance has been done, and repairs and inspections of absolutely necessary parts have been completed. - For reference, the highest fuel efficiency record is 11 on the section between Ilsan and Seoraksan Mountain. The Ilsan - Boramae section gets around 7 to 8. @Reason for sale: We have recently given up on the gallery business, so we are releasing young timers for exhibition purposes. @If you simply want to study the W220 S600, we welcome your inquiries.
