TroySR71: It would appear that the car board here is dead. My question is, has anyone utilized Costco to purchase a vehicle?

I wrote a rather long response and lost it so here's the short version: yes, for a Honda and a Subaru, both pre-pandemic. The process is easy and there's no pressure to buy. The cost is pre-negotiated and they won't negotiate down but did offer certain incentives (discount for buying off the lot, they also offered some advertising dollars if purchased by month end... but again, this was pre-pandemic, pre-supply chain issues). The only real "con" is, with time and persistence, you may be able negotiate a lower price on your own but for me, my time is valuable and I prefer to avoid the aggravation. Some people like a price battle, some don't.

And contrary to what hclasvegas wrote, Costco does not "give you a price" but gives your contact info to a local dealer who arranges an appointment at their dealership.

In my experience with warranties, they're not usually worth it. We did buy (negotiated down) one on the Subaru because of all the cameras and expensive headlamps but have never used it. Back when I sold extended warranties (not cars) at my first job out of college, their invoice cost was one penny.
