Another 2 cars that had a lot of soul were the 40s something Tucker and the 81 Delorean.
The Tucker was way ahead of its time, colored cars, revolving headlamps, rear air cooled engine, etc. Also the Delorean was a big hit in a blockbuster movie with futuristic styling. Delorean was also one of the designers of the first GTO a while back.
Both Tucker and Delorean were innovators and were ahead of their time, so ahead that people were not ready for their designs. Not for a lack of quality or style, but due to finanacial backing did they fold. Gutful risk takers are perhaps the most soulful of all.
