I've been waiting to buy a car vac and this one has always caught my eye. Haven't seen it much cheaper than $160-200+. Costco has it for $139.99 until July 4th, 2010. Gonna see if they have it in store first. If not, I'm ordering it tonight! Costco - Metro 4.0 Peak HP Portable Vac & Blower
It's an awesome vac for sure. My favorite. Just remember, no wet vac capabilities with it. Just be sure to buy the cart for it too.
