A :Standardized" Runabout,,, [PIC}

Prior to 1908, automobiles were literally 'one off' handbuilts. Cobbling components for assembly amounted to laborious filing and hand fitting. Repair with replacement parts was equally labor intensive. For the 1910 model year, Cadillac had invested in precision machinery that finally offered standardized, interchangeable parts.

"To prove this to a skeptical public, England’s Royal Automobile Club disassembled three randomly selected Cadillacs, scrambled the parts, replaced 89 of them with service parts, and then reassembled the three cars “without fitting or scraping of the bearings.” All three started and drove 500 miles each “without adjustments of any kind.” 

For this, Cadillac earned the 1908 Dewars Trophy for the most significant improvement in automotive engineering. It would win the same award 4 years later for both its electrical system and electric starter.

The 1910 Cadillac Model 30 Roadster, although still keeping with "horseless carriage" chassis and coach design. offered a precision 33 HP 286 cid 4 cylinder engine. It didn't come cheap, however. It's price (with top) was $1795 which was 3X the average annual income.
