Funny! Yeah, I live in Williams Bay now and I actually work for an auto shop in Elkhorn. I sold the Dart in December. The only other dart I recall seeing in the area was a purple 67 Dart convertible in Delavan a few times.
There is actually a quite a few Darts around this area. Most of them hardly ever get driven. Once in awhile you seem them at the various shows are drive-ins around. Which shop you work at? I am surprised you have never seen my Dart sitting out for sale, I live right on the main drag through town. I finally sold it couple of weeks ago.
