How does the Chevrolet 3100 feel during overtaking?

It originally came with a 3-speed manual transmission, while many restored models have been upgraded to 3-speed automatic (TH350). For buyers considering the Chevrolet 3100, that matters because it affects how easy the car is to live with, whether for commuting, family use, long-distance driving or ownership costs. The useful way to read this is not as an isolated specification, but as a clue to how the car will feel in real daily use.
