Economy Car Rentals review: Don't use!

I booked a car through Priceline and received the price. When I got to the counter in Honolulu, they priced it $40 higher than price received online. When I tried to decline the insurance (because my credit card has that benefit), the lady at the counter would not let me decline. She then charged me an additional $90 for insurance. I ended up paying double of what was quoted. I will no longer do business with Economy or Priceline. The car I received was older than I expected. I have rented cars for over 40 years and have never received a car rental that old or in the condition it was in. Needless to say, I was disappointed with Economy and Priceline.
