If you think about it, the leaf on the logo would look odd anywhere else but where it is now. If it were on the bottom right, it would look like it is hanging too low and it would look awkward. The way it's positioned on the top makes it look as if the leaf fell on top of the sign. I do think it looks strange, but I guess they wanted to have a leaf in the logo (because of the title), and like I said, it would look awkward anywhere else. I'm sure they probably tried placing it down the bottom.
But what I don't get is that font on the leaf. Ugh. Such a bold yellow color outlined in black? Why? It would've been better if they picked a more natural-looking font and color, and didn't outline it in black. It looks like they're trying to sell a used car by placing an obnoxious, in-your-face sticker on the windshield. Just my opinion.
