Bryn has RX7 Restorations. He bought a lot of Sam's (Atlanta RX7) parts when Sam moved.

200K is quite a few miles. If you plan on making the car faster, or dumping a lot of money into it, I'd say to plan on a rebuild.

I think that you might want to see what Bryn has in TIIs. He should have one for sale. It has a lot more building potential. While initial costs and maintanence is higher, performance parts are easier to come by, and you get more power per dollar.
