Best website ever for rx7's is Rx7club.com
Tons and tons of very useful information that you can search through along with many archives. They always have the factory specs listed, options certain cars came with, etc for newbee rx7 owners. You can post in the 3rd gen section of rx7club, if you say your a girl they will jump on it right away and help with any questions you have

They are expensive though, cheapest I've seen for a GOOD one, that doesn't need a rebuild or body/interior work was for $10,000. But as I see 3rd gens they are an exotic and a supercar with the right work done to it so they are worth every penny they cost. If someone would give me one to kill a person, I think I would really have to think hard about my answer......seriously
