i was browsing amazon, wishing there was a book on suzuki based vehicles and all of the sudden two showed up. i was just wondering if anyone here had read either of them and if they were worth it.

I don't know about the Haynes manual but I know the guy who wrote the other book. John was one of the first in the UK to modify a Vit, I was one of the others and so was that bloke on the front cover, now what was his name? lol.
I have to confess that I haven't read his book yet but he knows his stuff, he writes for a 4x4 mag (4x4 Mart) and runs a Suzuki 4x4 club in Norfolk.
If you're looking for Suzuki books, I can recommend 'Suzuki SJ Gold Portfolio' by Brooklands Books, its a collection of road tests from around the world. They also do one for Track/Kick/Vits, but I haven't seen that one yet.

I bought the Haynes one from amazon about 7 or 8 months ago its pretty interesting i guess has a lot of history but only talks about zukis sold in the U.K. and it didnt really tell me any thing that i didnt know about trackkicks

If you can find it there used to be an Aussie book about Sidekicks/Trackers/Escudos/Vitaras etc.  Basically had a history, specs, and a compilation of articles by the English speaking automotive press.  From friends who had seen the thing it was a good read but I never picked it up.  Now I can't remember the name and haven't seen it on Ebay since I got back into Suzuki's.
