BEWARE BEWARE BEWARE and avoid at all costs. Yes they are cheap but their attitude and customer service skills are equally as cheap being well below any acceptable level of decent and professional behaviour. We left our vehicle with 36 miles worth of fuel available they left us with nil, in the car park at Heathrow. We had to wait well over an hour to rendezvous, with little explanation or good manners to explain the situation. We were just left to get on with it.. This review is genuine and written without malice or anger but with disappointment we were treated so badly. We managed to limp into garage to refuel but some one else might not be so lucky.
