I must make it clear that I am a motoring enthusiast and IAM Observer. Seeing that John had published something so recent and being aware of his reputation I bought it.
The Book contains a lot of excellent advice but is peppered with many "voice of experience" snippets which I tired of. I found that really good insights of the practical application of Advanced Techniques had to be gleaned from the extensive wording.
For an avid motoring enthuiast it will be of interest but if not it will be very hard work
