I wanted to provide some feedback to Kayak because there may have been a misleading claim made on my rental. When I went online to do my booking originally, it very clearly stated on the KAYAK website that I would receive a "Mystery Car" at Avis but spelled out that it would be a "sedan that seats 4 people". When I got to the AVIS counter in SFO, they said that it was a mystery car so it was up to them to issue any four door car, so they gave me a pickup truck which was not very satisfactory. First of all, it was not a sedan and second, the trunk at the back was an open bed which made it awkward to travel with exposed luggage. I pleaded with the counter agent that the website specified a sedan with four doors and they asked for my reservation and apparently it just showed a 4 door vehicle and did not specify a sedan, like the KAYAK website did originally when I hit the confirm button on the reservation. I would like to know how this happened because the only reason I proceeded to make the reservation is because the website specified a "sedan with 4 doors" but when the booking partner who provided the deal sent me the confirmation, sedan did not appear to be listed. I really don't appreciate this as to me, it is false advertisement and misleading sales tactics. I could care less what sedan they gave me as long as it was a sedan. But they insisted, all they had was the pickup truck which did not make my vacation enjoyable at all. I reached out to the partner that made the booking with AVIS and they suggested it is likely KAYAK's issue in what they may have printed in the ad. Regardless, I was the one who was out in the end, as I had an uncomfortable ride and ended up paying at least the amount of gas.
