This was not a repair shop- just a garage, but about 3 miles north of Flemington, when Route 31 was called Route 69, there was a white house with a private garage next to it that used to store the Lee Koger owned, Vince Conrad driven circle 9 coupe and sedans. Actually one of the sedans was junked in the woods located to the right of the house & garage. Currently it's the home of what might be a tree triming contractor, but might still be the same family. We drove by it on our way to Flemington from 1960 thru 1963 and on. Always looked for that sedan among the trees. The property might have switched hands when the sedan was removed from the woods.
