I have a 1917 D35. I'm by no means an expert, but believe that this car is nearly identical other than 4 cylinder engine vs. 6 on the D45. Photo below is in my garage next to a Model T (mash up of several years). The Model T Touring is 3 door (driver slides over from passenger side) because there's not much space between the wheel and the front seat. The Buick has what I've been told is called a "Fat Man" steering wheel. In the photo it's in it's raised position. Then just slides down to a more normal state once the driver is seated.
