St. Louis area Dodge dealer sold a 68 c hevelle

[68chevelles]

I Believe a 1968 SS chevelle was sold in 1968 as a used vehicle at a dealership on North Broadway from a Dodge dealer that may have been a Harrell car or left there and had some work done to it by Harrell. Anyone know of this dodge dealer's name and how to find records of thier used cars.. The used car's salesman name might have been Jim Guthrey.. ring any bells? btw car was blue
