I have one thought:

Review Section: When I was researching cars, I went to various
sites to find reviews. The advantage in greenhybrid is that we can
list pros/cons, and our review can be linked to our own car data.

What I hated about other sites' reviews was that you can read
someone's review, but have no idea about where they were in
some cases, no idea about their driving conditions, and
no follow-up information on how their cars performed after their
reviews. Here, a potential buyer can read the reviews AND look
up our cars' performance and see our ongoing posts. Then, they
can make a better decision as to why we praise our cars or
are frustrated by them.

Plus, with our growing list, the number of members is already
larger than many of the sites I had seen, so we should end
up with a large range of reviews, both good and bad, for each
type of hybrid.

Just a thought,
