Help an aspiring author out, Oppo!

So, some of you know that I'm writing a novel (indefinitely). Let's face it, I've been working on that novel longer than Brian from Family Guy has been working on his. The process has involved a ton of research, but there are still some car-related facts that I need help with.

The protagonist, a Philadelphia gentleman with a bit more wealth than common sense, drives a brand-spanking-new 1912 Pierce-Arrow Model 66. The only thing is, I wasn't quite yet born in 1912, and I don't fully understand the mechanics of Edwardian-era motoring. How would one start a car in those days? Did you simply turn a key in the ignition, or was it a bit more involved than that?

Help me, Oppo. You're my only hope!
