yup, since you will be a second ownwer you will only have a 5 year 60,000 mile warranty. And yes Isuzu is very proud of their parts, I believe Isuzu wanted $1,000+ for a CV. Luckily I found one in a junk yard down south and got it for $100. I think they wanted $400-$500 for their alternator but I found a used one for <$100. Of course I abuse the hell out of my car and most likely you won't have to replace as much as I do but parts seem to be near twice the amount of Chevy/GMC.
With that being said, I don't mind paying the extra for driving such a great vehicle. And I am a broke/cheapass
