Couple of quick questions.

Flat pack all the way, or even a complete chassis. I have just cut and welded my own together from lengths of box section, and personally all the time and hard work in some ways I wish I had bought a flat pack/chassis myself. However I did get a lot out of the experience and something I can say 'I did that!'

Not that many pinto sierras around, on which the book is based. So you will have to do some mods that are not detailed in the book unless yoou get a pinto so I would not be too put off by building the mx5 version.

Mig is easier, but a Tig would be useful as you say. Considering buying one myself.
