I had an early Sonic Hatchback rental....... report here .

Massive improvement on the deeply dreadful Aveo, for sure.

It beats me why the Aveo went back from being the Group A sample car to Group B. Since seemed to keep the Aveos for a season beyond the natural expiry date, you would have thought they would have become the obivous cheap and nasty bottom of the rung rental vehicle. If a Rio is now Group A, I would far rather have one of those than an Aveo.
