I'm looking to find some reasonable car rental rates on 22 November for 4 days. The cheapest I've found is over 100 USD per day using kayak. Is this normal for NYC?. I only need a small car...
I don't know how you're using it, but when I run a Kayak query from the airport, I get about $47 a day.
However, remember that you're looking to pick up on THANKSGIVING. As this is a public holiday and the start of a long weekend, it's highly likely you'll pay extra charges or that rentals will be in demand as people return home to their families or travel for the long weekend.
