Congratulations! When you feel like it, perhaps you could add details about your Wagon into your Signature (via the User CP at the top right), as well as your MPG on the appropriate thread. I assume you have the 3.7 engine from your post here, so this would be one possible MPG thread:

Not sure which rear end you have.
Thanks
