The book is a quick read at around 200 pages. Fun anecdotes as he rambles along about his Porsche rebuild. Its something to give you hope if your 914 currently resides in the driveway... and in the garage... and in boxes and baggies.
Not to much revelating info on the technicalities of the rebuild, but a decent idea of what it takes if you've never attempted it before.
Bottom line: Enjoyable.
