Budget/Avis is getting there. I had an absolutely horrible rental at O'Hare about five years ago. Rattles and squeaks and probably 50,000 miles overdue for an alignment.

Last fall, I got an almost new Mazda SUV from Avis. I was 3 miles down the road when a Service Engine Soon message took over the entire center of the dashboard. I hope they got it serviced after I returned it the next day.
