I've got an example of what the Motor City can do from the days when the world turned to Detroit for engineering excellence...
Roller cam, full-flow cooling system, cockpit adjustable shocks, more power than 2 Fords put together - Packard. In 1932, Packard engineering was able to measure materials to one millionth of an inch. They introduced the world to the V-12...in the year 1917...the "H" shift pattern and had built engines for racing airplanes and the Navy's Zeppelins (that were specified to go hundreds of hours of continuous running without inspection/maintenance).
Detroit starts building them like that again...that kind of excellence in engineering, styling and performance...and you won't have to have some kid with attitude hawking the goods...
Oh...and in case you're wondering, my '32 Packard gets 15W40 Rotella for that magnificent straight 8 engine...
