We're glad someone took the time to look into this 30-day guarantee that Chrysler is touting: The Detroit News reports: Chrysler's '30-day, money back guarantee: What's the catch. Check out this arithmetic:

Let's start with a restocking fee of 5 percent of the stickerprice (ouch!), add in the 50-cents per mile usage fee (yikes!), all the sales tax (what!?) plus finance fees, title, tag and registration (grrr!).

Total it up on a premium ride like a Jeep Grand Cherokee Overland, and returning a car you just purchased for about $34,000 could easily cost about 14 percent of the total purchase price -- more than $4,600.

Aw, forget the bratwurst and beers.
