Bought Milo, my 92 300D and my first MB, back in 2003, with 137,000 miles on it for $5900. Nothing wrong with it....lady who owned it simply wanted to get an Acura MDX.
Knew absolutely nothing....I remember complaining to Firestone that they forgot to change my oil because if was still black!

And I remember thinking that, now that I owned a Mercedes, I wouldn't have to worry about car repairs as much!! haha (It replaced a Honda Accord.)
Had thought I would keep it forever....and invested in it accordingly. But things change....and, my wife's current 3 MB limit being a reasonable cap, I had to sell Milo to make room for Winston.
My only consolation is it is staying within the extended family....will be my best friend's son's daily driver. Just graduated college, got married, begins a teaching job in the fall....will drive Milo for his 45 minute commute.
I'm sure I'm not the only one around here who ended up selling his sentimentally-attached-to first Benz. It was my daily driver, then my daughter's, the mine again, the my son's. For 120,000 miles it served our family well.
Milo spent it's first eleven years in Bucks County, PA, then moved to TX with me, then to RI....now it heads back to Bucks County!
