My guess is that there only about 7 to 10 owners of Elises or Exiges in the state, and about 5 0r 6 who are active on this board. I just purchased my Elise in March from Hollywood to Central Wisconsin.
As you can see, prices for good used cars are very reasonable. I wouldn't limit myself to the Wisconsin area to get what I wanted. Even with shipping costs, it is still a good "value" if you find the right Lotus. By scanning the L.T. Lotus Cars For Sale subforum you get the best possible variety and the opportunity to learn about the previous owner. With due diligence and lots of detailed photos I was able to safely buy my car without ever traveling to California.
I hope you're successful too. Good luck.
