Rental car prices are nuts right now.
I finally pulled the trigger on my car rental for my Iceland trip... got hosed due to the supply/demand.
Just for fun I compared a similar trip in some US areas and prices were not as far off as I imagined.
Last year the rental car companies sold off their fleets and have not been able to purchase enough newer vehicles to replace them.
In Florida, people have been renting Home Depot trucks/vans and using those as rental cars to go to Disney etc
