Not BL Avenger - Hillman and then Chrysler.
I had one as a rental car on a visit to Britain in the 70s. I thrashed it for two weeks including a final drive from Skye to London in one day (pre-bridge days). It was a bit down on oil when I handed it in!
Chrysler sensibly realized that a 4-cylinder econobox could not be sold as an Avenger, so it was rebadged as the Plymouth Cricket (as in Jiminy)!
