Which S-Class trim fits a driver who does the commuting?

The S 500 4MATIC® and the S 580 4MATIC® share a 9-speed automatic and all-wheel drive, and the EPA certifies both as hybrids. The S 500 4MATIC® is EPA-rated 23 mpg combined and the S 580 4MATIC® 20 combined.

The S 580 4MATIC® is the trim to start with if you want the higher power output of the two. The S 500 4MATIC® is the trim to start with if you want the lower MSRP.

Which S-Class trim fits riders in the back seat?

Riders in the back seat care most about room, and the S-Class offers it in both trims. The S 500 4MATIC® and the S 580 4MATIC® each give rear passengers 43.9 inches of legroom, so back-seat room does not separate them.

From the moment I walked in, he was incredibly welcoming and just so nice to work with. He made everything feel easy and actually enjoyable. He is truly one of the most genuine people I’ve ever met in this industry. He didn’t just feel like a salesman, he felt like someone who truly wanted the best for me. He is so helpful and knowledgeable about the cars, and he took the time to make sure I was comfortable with every detail without ever making me feel pressured or rushed. I would recommend Aykut to anyone and everyone looking for a new car. If you want someone who is professional, honest, and just a great person to work with, go see him.
