My name is Grant and I'm from Edinburgh. Love RX7's (FB, FC, and FD) and have them on my radar as a next car this summer.
Looking forward to learning more about the FB, and seeing some of your cars on here - and maybe even in the flesh if there are any in Edinburgh! (and hopefully watch the classifieds soon)
From what I've seen on-line. FB's can be picked up in decent shape for 2-3K, which would allow me to plow a few K into making it how I wish.
Here's a picture of my current car (also an oil muncher):
