(3.50 stars)  On and off, Enterprise Rent-A-Car has been a go-to for business travel over the years.  We had been horribly let down at a critical time a decade ago and have approached Enterprise selectively since then.\n\nHaving the whole family in tow for our vacation means that only a minivan will accommodate all of the luggage, and Enterprise had one for us at a marginally-acceptable price.  Arriving at the Phoenix Sky Harbor Car Rental Center (a considerable distance from the Airport), service at pickup was excellent; friendly, helpful and efficient.  Although a bit slower when returning the Chrysler Town & Country, it remained friendly.\n\nAt pickup the minivan had only 4,100 miles on the odometer, yet had an annoying squeak in the front driver-side wheel when driving at highway speed.  All told, not a bad experience, but the service from Enterprise was extremely good.
