Essential Modern Middle Ground Book,
This book, however, is a really superb rendition of modern guidance, with superb photographic essays of complex operations. Although it has a color cover, all of the photographs are in black and white. The book is a real build on top of a normal repair manual, with sections on history, buying (BUY THIS BOOK BEFORE YOU BUY AN MGB), and then bodywork, interior trim, mechanical, electrical, and so on.
The third book that I recommend is Anders Ditlev Clausager's “Original MGB With MGC and MGB GT V8.” This is a coffee table book, a “this is what perfect looks like,” and it is both inspirational and just plain delightful. I drove my 1964 MGB across the country in the four days after I bought it (at 2500 RPM most of the way, 65 mph, but on special stretches of Iowa, doing 4000 RPM for sustained periods) because I love this car as a sports drive, not a driveway show car. Still, it is really great to see what perfection without regard to long haul rallying looks like, and I could not do without all three books.
