Now, lets not criticize the Mercedes Corporation for doing what I am sure is a great job of creating timeless masterpieces, lets instead be criticizing an American business for allowing its employees to act in a brash manner that contradicts the very essence of the product in order to be condescending and flip.
I recieved the same treatment by employees of a Chevrolet dealership when I pulled up in my first car, a 65 Impala, and inquired as to the availability of any parts that I could fix it up with in the mid-80's. Consequently I have never purchased a new Chevrolet car or truck. A Yugo, a Hyundai, and a 2yr old Saab but never a new or newish Chevy. The Yugo place was the most fawning willing to say yes to any suggestion to make the sale except when it came to hubcaps, those had to be payed for cash up front $200. I painted the wheels instead. Now back to the dash....
