My first impression was that it is an exact duplicate of Google, just by looking at the front page. Once doing a search for Subaru, I quickly realized that it is in fact nothing like Google. Definitely a cool idea and very nicely implemented. I would probably try and change up the front page a bit though to avoid giving the impression I got when I first looked at it.
I agree that it looks like a google clone, but what is offered when you enter a search is pretty sweet! Create some graphics that can separate the home page from google and i think you are well on your way.
