The only thing I would mention about Budget in Europe is that if you care about your ff miles you will earn (350 for most airlines), it will be a struggle to get them out of Budget. They are by far the worst on that in Europe, with Avis and Hertz next. On a three week trip in April, two of the three rentals were from Budget. Previously, Budget had been like Hertz and Avis and never applied the miles until a missing miles communication was sent, and then they did. This time on an Ireland rental, it took three communications to get the miles and after 5 communications for a UK rental, I still do not have the miles. On the other end of the spectrum, Europcar miles have always posted automatically with no hassle and National has most of the time, with only one communication necessary the few times they did not.
