Interesting model, but I predict we'll see it way before 2029. We're not going from the first engine to the first mass-produced automobile, and manufacturing, technology, and operations improvements are orders of magnitude higher than a century ago.
Absolutely correct, my crude estimate is an upper bound.
The Ford Model T sold for $850 in 1909 ($2012 21,390), $550 in 1913 (12,580), and $440 in 1915 (9,640) [1].
Also, noting that the Ford Model T was on sale in 1909 (t=31) I revise my original estimate down to 2025 (t=22). Assuming 2% CPI inflation that means {$2025: 27,670; 16,270; 12,720}.
