OK I may be on crack on this... so bear with me.
I remember reading somewhere, it may have been the manual, that you can "push start" these cars by pushing in neutral and dropping the transmission into 2nd (all the way down)... is this true??? I remember reading and thinking that was crazy.
It may have been in the manual for my 300SD I had... not sure about the 300CE manual.
If this is completely insane, just let me know... not that I am going to try it EVER, but if it's possible, might not be a bad idea for this 300E he's looking at.
