I always like to get a Chilton book on all the cars I purchase just so that if anything ever happens I can flip through that book and see if it is a problem I can handle myself. Do they make a Chilton Book for the 2003's yet?????If not do you guys have another book you can recommend

Haynes books at O'reilly for about $12 or less. Should work for about 95% of the 2003 Xterras.

FYI, the Haynes and Chilton's books are virtually identical.
