Love my Mercedes
I have been driving Mercedes Benz s class vehicles for over 10 years, traded every 3-4 years and have been very happy, always have them serviced at the dealer, always received a loaner, no complaints.

An Absolute Dream
I have owned 6 S Class (SonderKlas) cars in my life and each and every single one has been problem free and a pure joy to own, drive, and admire. The 2021 S580 however.. Well this car is truly something special and not an incremental upgrade! This thing is crazy

Luxury at its best, you can’t get better than that with this price range. S 580 is the way to go, the 8 cylinders are so smooth yet so sporty. This car can be Rolls Royce luxury and lamborghini urus if it wants

Vel is a great sales guy.
Vel is a great sales guy. Very responsive and will work with the customer. We drove from MI with a trade in and they honored their offer. There were a couple minor things like steering wheel was more worn than we would have expected given the nice condition of the rest of the car. Small headliner plug interior for convertible top was missing. Other than that it was a smooth transaction.
