Cool thread and great grab Bill!.
Love the family dealership thing also how you're your grandfather's namesake!.
Some of the greatest times of my life were when I worked at a Benz dealership too...summer weekends w/ new SL's, speed & girls are an impossible combination to beat...or forget!.
I had some fun w/ early Z-cars and 510's too also have been waiting patiently for a clean 510 Coupe to roll into my life again someday...B Sedan racer maybe?!
Check the front inside framerails Bill and get some Boeshield or something in there if all's Ok..
I repaired a few of them back in the day and rust seem to pick on those areas first..
