1906 Cadillac Model K Navigation
By the mid-1900s, under-seat engines were losing their styling appeal, so Cadillac disguised the fact by mounting a dummy hood over the front axle, with a vertical radiator at the front, on Model C, E and F. These models were replaced in 1906 by Model K and M, which differed only in wheelbase (the Model M was two inches longer). The M and K continued into 1907, where they were joined by Model S and T. The Model T would continue in production until 1908.
This Model K Runabout was purchased by the current owner's father in 1952 from the original owner. It was stored for many years and is believed to be a 1905 model but had been 'updated' with the addition of running boards and modified by replacing the boat-tail with a box.
The car has been treated to a rapid restoration which took ten days to complete with workers working around the clock in three shifts. The car participated in the 1953 revival Glidden Tour from Cleveland to Columbus to Dearborn, Michigan. During that year, it was also the recipient of the Thompson Museum Trophy for the finest restoration of an antique automobile.
In 2002, the car was given another professional restoration. It was completely rebuilt cosmetically and mechanically, including aluminum pistons for reliability. It was shown extensively during 2002, Cadillac's centennial year, including that year's Meadow Brook Concours d'Elegance. In 2003 it received an AACA annual Grand National Award and was recognized as a Senior Grand National First Prize winner in 2004.
The car is powered by a 98.2 cubic-inch horizontal single-cylinder engine that offers 10 horsepower. There is a two-speed planetary transmission, dual differential-mounted brakes, and a wheelbase that measures 74 inches.
In 2012, the car was offered for sale at RM Auctions sale in Amelia Island, Florida. It was estimated to sell for $100,000 - $120,000. As bidding came to a close, the car had been sold for the sum of $99,000 inclusive of buyer's premium.By Daniel Vaughan | Mar 2012
