I booked a weekend car hire from Bristol Airport recently. The price for the hire was the most competitive I could find. Having booked a small car, when I arrived at the Green Motion premises, I had been upgraded to an almost new Kia Sportage. It was great to drive and very comfortable. Having supplied all my details online a few days before, documents checking was quick. Be aware that the £1200 excess is added as a “pending” transaction to your credit card but is removed shortly after the hire is completed. Staff were helpful and, despite other negative reviews I have read, I really couldn’t find any fault with this hire at all. The premises are just outside the airport boundary but, on a dry day, is a pleasant ten-minute walk. A shuttle bus also runs regularly to and from the terminal building.
