Great thread Mike.
I think Jay is your kind of car collector, he looks for unique and technologically advanced cars for their day.
The 1925 Doble Steam Car, probably still the most advanced steam car ever built.

There is also his Baker electric car of 1901.
Very useable and advanced car for its day.
Both overtaken by gasoline.
