Allpar.com has a wonderful article
on the development history of the Chrysler Horizon/Omni, focusing heavily on its European roots. Seeing as how I knew absolutely nothing about Chrysler's involvement in Europe during this period of time, and the similarity of this development process to the "world car" exercises that are still common, it's a fascinating piece of writing.
Even though the Horizon and Omni are rather humble pieces of transportation, their contributions to Chrysler's survival throughtout the 80s shouldn't be underestimated, and indeed they were among the, uh, least awful
of American compacts during that era.
