Presently have a 2018 E400 Cabriolet. I really like the handling and the looks. Love the rear seat room vs my previous BMW 650 convertible. I do miss the V8 and the sound of the BMW. Once used cars prices settle down and leases expire I am considering a 2021 S Cabriolet. Couple of questions:

Is the rear seat room the same as the E400?

Is the AMG version the maintenance hog that I hear it is. I only put about 3k a year on these vehicles in Florida.

Thanks for your input.
