Kasey,
When I looked up those ads I specifically set earlier date parameters and nothing came up. There are of course other Wilson Chevrolet's scattered around the US but I didn't see any others local to W. Va. When I am researching dealerships for my reproduction documents I often contact the local libraries or local historic societies within the state or city for more information. Many have older city directories of business listings. I use these tools to ensure the dealer's address at the time of sale for each car as many dealer sdo move around throughout the years. Here's the link to Morgantown's public library, looks like they may have 3 branches but they'll let you know who has the older directories when you call. Ask them to pull 1967 directories and 1968 and see if Wilson is listed in both. Good luck, Paul
