Have used AVIS 4 times in the last two months. Helpful (if a tad apathetic staff) never any problems with pick up / returns. Call centre responded quickly. Able to use frequent flyers when connected with Jetstar flight & accrue when not. Rented a range of cars, from a Hyundai accent to a Yaris - all clean and in good order, very few Kms so like new.
Definitely my preferred rental car service.
