I booked through Hotwire for a rental car as a suggestion from these boards. NOT GOOD!!! We were told we would have a Monte Carlo or comp. and when we arrived all Hertz had left was a Mustang. A family of 4 on vacation for 14 days with luggage in a Mustang, lol. So, I was forced to upgrade at 15.00 a day more. I could have booked an Explorer for this length of time for 399.00 instead, we ended up over 600.00. I have emailed them and have basically been told I agreed to the upgrade!!! Don't use Hotwire!!!
) but they tried to give you a 2 door Mustang and then strong-armed you into paying more for a bigger car, then they were wrong. I would take the matter up with Hotwire. I've found their customer service to be very nice.
