Absolutely terrible. I travelled to Newcastle for my mother's funeral, and needed a hire car for a couple of days. I booked a week in advance, but when I arrived to collect it, the staff at their Newcastle Central Station office made no effort to give me the car I had booked. Instead, I was given one of the three Vauxhall Crosslanders they had on their lot. I specifically didn't book a small SUV because they have terrible fuel economy, but was given one anyway. When I got to the car, the front interior has been cleaned but that was it. The outside of the car was filthy, to the point where I could hardly see out of the rear window, and there were dead leaves trapped between the door and the door frame that had clearly been there for several months. The irritating excuse for a customer service person kept saying "sorry" but clearly wasn't. Still, I suppose sarcastic mealy-mouthed apologies are easier than actually fulfilling customer orders. I returned it after a day, and I'm still waiting for my refund. Of all my car hire experiences in the UK, Europcar is by far the worst.
