Wow!!! How did I miss this thread! Are you guys arguing without me!!
Okay there sunshine(s). It's simple math. Let me break it down for you...
1) when you purchsed the H3 you should have seen this nice big fat sticker on the window that showed what your gas mileage would be Hwy and City
2) Assuming you're no stranger to driving, one would think you would have a pretty good idea about how much you drive around. Home to work, work to home, home to the support group meeting, etc...
and Lastly...
3) Also I assume that you've kept your eye on the rising gas prices for the last 2 years or so, (this one really should a no brainer)
So...my point....It seems pretty clear that you didn't do your math before you decided to purchase your H3. Had you done that and still wanted the H3, you could have found an answer to your question prior to buying. So...really....you have no one to blame but yourself.
Oh...if you do find a real answer...be a dear and let us know.
