Renting a car for a week. I could save some $5 per day, but I'd have to put up with a "mystery vehicle" from the lot. Would you play the game?

My local car rental places all have the same type of promotion. For $5 off per day, I get to accept a "mystery" car from their lot. This can be anything from an economy car to a full-size SUV. <br><br>Pros: save $35 for the week. <br><br>Cons: accept whatever vehicle they give me, including a tiny 2-door economy car. I have a car seat, small cooler, luggage, and a few tools for a work project. If I get a tiny car I could fit all my work stuff in the car, but my wife and daughter might not have enough room.<br><br>Given the potential downsides, would you play the game and accept the mystery rental?
