Nearly 100 years after the Czar of Russia gave the Prince Regent a droschki, the motor car was becoming available to those who weren't massively wealthy. This doesn't mean the cars were cheap, especially the ones known for high quality parts and construction.
I'd never heard of the Moon Motor Car until I happened on an enquiry in the local newspaper. Naturally, nerdy historical sleuthing was in order—and you'll easily imagine my excitement at finding advertisements like this one in a WWI-era magazine.
In case you were wondering about monetary values: According to dollartimes, "$1.00 in 1916 had the same buying power as $21.28 in 2011." In today's dollars, therefore, the "New 1917 Six-66" was $33,516.
