Well I did it, yesterday picked up my 2017 Diamond Silver metallic wagon. It was a very long day! Booked flight to Buffalo from Dulles depart 11:15am arrive 12:39, left home at 6:30am ,flight delayed by over 5 hours actually departed 4:49pm. Mercedes of Buffalo stayed open for me, car was on the showroom floor and they picked up on the id I had sent them it was my birthday - they all wished me a happy birthday - nice touch, signed paper work covered the basics of the car, its my 3rd "newer" MB, Left dealer at around 7pm drove home 477 miles, got home 3:43am. Car was AMAZING! comfortable, chewed thru miles without beating me up. but a little weary today, biggest bonus MY wife likes it! Car has 39.5 miles with 3 year MB certification not cheap, was an ok deal - there are only 14 2017 & 2018 MB certified wagons in the country as of today, so any deal is good.
