Yes.
In the early 1920s Christian Fredriksen an Australian tried to market its Acme Spring Suspension System in the UK and USA. Using two sets of three cantilevered leaf springs, the system spread shocks along the length of the car for a smoother ride over rough surfaces
He was not succesful but the local Summit, built by Kelly's Motors between 1923-1925 featured Fredriksen's suspension.
Additionally if you look around the net, you can find that it is claimed in many places that Kelly's Motors was the first to feature a car radio as equipment in its car, presumably the Summit. However this claim doesn't appear to be true...
