So, we turned around, and went to look at old cars. It was the Whiz Motor company of Chappell Hill
I'm saying that very much as a non-expert on horse-drawn vehicles, especially American ones, but what you see here is a pretty sophisticated piece of work, lightweight, agile, strong. Low unsprung weight. Look at the red parts, lightweight, slim wheels, very lightly dished. Note the axle camber, which leans them subtly outward. I'd better not get into the subject of chassis geometry. Cambered wheels go back a ling long way. but the really neat thing you see here is the suspension. Three-point attachment, the rear of the body sits on a frame which is mounted centrally to the topmost of three multileaved semi-elliptical springs. Roads were rough, but this arrangement would allow a lot of movement up and down of either or both rear wheels, without transmitting most of that to the passengers above.

Isn't the internet amazing, I even found the guy who drew the sketch that became the logo......
The little town of Chappell Hill has some nice old buildings, but it was not exactly buzzing with activity.
