Many years ago, I had a 1983 MB 380 SEC. It was the coupé version of the W126 S-Class — it was a giant rear drive 2 door version of the S class, chock full of technological advance of the day, including a seat belt presenter (really). At highway speed, it would lower itself. It wasn’t fast off the line, but it was an autobahn cruiser. I drove it to Virginia and back several times and it would lope — at 90mph, it was practically idling, running at 2200 rpm. (I never pressed it to see what the top end was). I was rear ended in it by a Volvo, whose front end was destroyed; The big Benz never got so much as a scratch on it. It was solid as a bank vault.
The new most up to date version of the S coupe is out, and the it is Twin-Turbo 4.7L V8, 449 HP / 516 LB-FT, 7-Speed Auto, All-Wheel Drive S550 4MATIC Coupe was just named Automobile Magazine‘s Design of the Year. My current lease (Infiniti M) is up in March 2016, and this would make a lovely replacement (if I could get Mrs. Big Picture to say yes to it!):
