If you are restoring or considering purchasing one of Jaguar's XJ series sedans - this is virtually required reading. The book, well illustrated and featuring all known derivitives of the cars (such as Daimlers and the limited production coupes), is probably the most well researched guide you can own. It identifies not only what's correct and authentic when it comes to appearance and options, but what the weak spots and possible faults are as well. Featuring what seems like 100's of color photos, which must have been shot specifically for this book, this one should be on the shelf of every Jaguar lover's library.
