I got that yellow Costco shop vac for around ~$60 when it was on sale.
I think it works well enough as a car vacuum although the hose that comes with it is a bit short and and
rigid. I don't use the wiry brush attachment that it comes with though. I got a much softer horse-hair brush attachment from my parent's recently broken vacuum.
But if you're going to end up buying a longer more flexible hose and other attachments, you might as well just shell out the extra for the home depot vacuum:
