Hard to say i got both for my car but the Chilton one covers more years than the Haynes does but yeah hard to say it was the Haynes that saved my butt when i couldn't find the starter and was stranded in the middle of no where but then again i never gave the Chilton a chance at that point. But i'm guessing most people are gonna say Haynes cause it's been around longer i think and is usually the standard. Having said that my dad told me to get both so who the fuck knows get em both.
