<prompt> Human: We are looking into getting a new car. We love Costco. We are curious what you experienced, your perception of pros and cons, etc. Thank you.  <response>: I havent actually used it to buy a car, but its just a referral program essentially. Costco connects you with local dealer, and the dealer promises to sell you the car at a previously determined low price.It can take some of the hassle out of negotiations I suppose, but you should be able to get a lower price working with a dealership directly.
