Hi, were booking a trip to Hawaii from the US (domestic travel) and looking for a cheap car for 5 days. We stumbled upon wisecar on kayak but the price of the car for 5 days is way too low to be true. When we book through them the option said we would get a "surprise" car rental company after booking. After booking it said our car rental was Thrifty but when we called there was no reservation because our voucher doesnt even have a reservation number. It looks like half of the reviews online said they showed up and there were no cars available after booking.
Is this service legit?
