If you read our blog, you know we're fans of the programs where we can reserve a car that meets minimum characteristics (such as mid-size or full-size) and then select any car available among a selection made available for members. Our team members rent a lot from Hertz and National due to these factors (Avis' selection tends to be underwhelming or non-existent) but we had never encountered an example where a vehicle in the allotted area was off-limits, theoretically due to a law. We have encountered a situation where a National Executive Aisle car wasn't available because National "gave" part of the Emerald Aisle to Enterprise for "convenience", but never have been presented with the idea that there's some form of legal restriction. I had selected my desired car from the Executive Aisle -- the 305 HP 2018 Chevrolet Impala V6 Premier, the almost-official car of the AutoSlash team -- and got to the security gate. And the representative made me turn around to pick up a different car.
