This the sort of company that advertise good deals but be really careful when booking with them - I booked the car with Mastercard but once I got there they didn’t accept it which made me take the “full cover” (half the price of the rental!!!). I’ve been using it for other car hires and fair enough it’s a debit and not actually credit card but my point being - in that case they shouldn’t allow bookings with that considering they do not accepted that sort of cards!! This is just a very sneaky way to make you pay more straight away when you have no other option. It happen the same thing to the couple that collected the car just before us - so it’s a routine thing I would say. Upon drop off they left us at the BP station at Glasgow airport (1pm) because the driver run out of credit in the card to pay for short stay/airport drop off…. I think that says it all! Also - the car was all beaten up and not that clean inside.
