Could not use the carcash OR my credit card. System would not accept my UK card despite having used it for the original booking. Ignore the review below. Sorry.
This is my review and I am awarded $10 Car Cash from Carmel for sharing it.

I've used Carmel a few times over the years when arriving at JFK to get to Manhattan. Easy to book on line. Sometimes a bit tricky to let them know I've arrived at the terminal but overall, a good service.
