I have an '88 420SEL which I got last year for my 17-year old daughter's first car -- a grandparent's trade-in at our local dealer with 75,000 miles on it which we fully refurbished (details at link below). She has driven it for a year and we use it for family road trips to keep the mileage down on our leased cars -- runs like a locomotive on the highway -- just back from a trip to Jekyll Island averaging 80MPH all the way.
We have put 16,000 happy miles on it but have switched her to a '93 190E Limited Edition with factory Sportline as she wanted something smaller and more maneuverable, so have decided to sell it as we have four cars (wife has an Infiniti QX4) and three drivers:

Will get some pix soon to add to post -- a great Southern rust-free fully-renovated 126.
