I dislike Enterprise for the way they ask about your existing insurance coverage...What is your insurance company? How much is your liability coverage? It's all a technique to pressure into buying their add-on insurance.
I've avoided them completely for years, but yesterday had to take a car in for service and was offered an Enterprise loaner car. The sales rep excessively chatted me up, then got into the rental car with me and asked how much liability coverage I had. Since I have insurance for my personal car, plus was using an Amex card with their primary coverage, I merely replied "Plenty of coverage."
She wanted a number and was not happy with this answer
I noted that she was helping Enterprise do its market research by asking the make, year and model of the car that I had taken in for service.
