I have only had mine M715 since Oct.'09 and have not driven it too much, still a driving project. But...
Coming home from work at one of the busiest intersections in Louisville, KY at a stop light, waiting for the green, middle of traffic thinking to myself 'don't quit, don't quit' (before the carb was overhauled). I glanced out the window down to my left and this little kid in the car next to me, his window half way down, both hands on the top of the glass, peering above his window says, "Neat truck Mister".
That little kid, maybe 7 or 8 years old left an everlasting impression on me. I will never forget that! WHAT FUN! Ken
