Not sure if Budget qualifies for this thread, so let me know if it doesn't...
I am National Executive but they were sold out for a last minute one-way I needed as a result of a flight cancellation.

Status: Budget Fastbreak
Location: PHL one way to ABE
Booked: Fullsize
Offered: This location has 'zones 1, 2 and 3' for Fastbreak members to choose their own car. I didn't receive a text/email directing me to a zone and went to the counter. The rep told me to choose anything in any of those zones. Cars that were available included a CX-90, Outlander, Malibu, Kia Soul and Outback
Received: Chose the Outback - had PA plates and only 900 miles on it. Enjoyed driving it.
