I was reading on the old forum about people getting quotes from the Dealer for $450 to $700 for the 30,000 mile service. Others said that you can do it all yourself in the driveway. Others said that you can get it done at a Mom and Pop shop for $150 - $350. I always thought I'd spend any amount on my truck to keep it primo, but it's just fine and now that the time has come I really don't want to donate $500 to the dealer afterall. I have a supergood superhonest Mom&Pop shop on the corner that I trust about 10 times as much as my dealer so I'd rather go there, but what I am really worried about is that if my engine ever blows the dealer will not go to bat for me on the warrantee because I went somewhere else. Or would they be just as glad to have the warrantee work all paid for by Isuzu if the worst ever happens, and not even care who has done the service in the past? And how much have people been paying for the 30K service recently? I am feeling really cheap these days!
