First of all, Costco is not a true buying service per se. But, they are a good starting point in a search for a new vehicle. In most locations they may only have one dealer of a particular manufacturer that they deal with. In my case they had none locally and the closest one was 110 miles away. But,that still worked out because we were able to eventually come to agreement and they provided free delivery service.
Dealers do not generally provide vehicle invoices and even with a Costco customer hat is still true. What they do provide is a Costco customer price sheet. Took this directly from their website. “After you have selected a specific vehicle at the dealership you are shown the Costco Member-Only Price Sheet, which clearly breaks down the vehicle price, savings and any additional rebates or costs.”
They are just hoping you are naive enough to say thank you, we’ll take it since it must be the best price if Costco backs it. LOL. It’s really nothing but a starting point that you can get from any other dealer out there at anytime. It’s a negotiating starting point and that’s all. We ended up getting our last one from the Costco dealer but that was only after negotiating another $2000 off of their “Costco price”.
You are getting nothing from them that you couldn’t get from any other dealer. I take that back. At least in our case they waived doc fees for Costco members so that saved us another $595. Don’t know if the Costco dealers all do that but I kind of doubt that.
If you are a costco member, use the service to at least get a starting point. Then be ready to negotiate.
