Headlines should grab attention and draw the reader into the text. While this headline is nicely off-beat, and does use a question format to create involvement, in the long run it doesn't work. There is no obvious relationship between frogs and car sales, so it initially seems like a waste of time to read further, which immediately reduces the number of dealers who get down to your pitch. This first thought in the piece does not offer any good reasons for caring, or reading about the company's services. The hand-drawn picture of a frog on a lily pad snatching a fly from the air looks a little cheesy.
People look first at pictures.
The role of the picture is to intrigue and entice them to read the headline, and to help create the mental launch pad for pitching your message. This picture doesn't help set up your pitch, because it is not even symbolically related to the message. The first sentence should be tossed, too. No one likes to be told they don't know something, even if it is the price of caviar in Stockholm. Subconsciously it diminishes our self-image.
