Well been looking for another diesel for awhile now. Local dealer got this is for trade today, 2007 classic ccsb, 125k miles, had a hyertech chip I believe, no longer has it on there, drives pretty good, power everything with sunroof, I am going to get them to put stock rims back on with some new mickythompsons atz. Needs 3 new tires anyways. Talked to orig. Owner and said he had the whole front redone(ball joints,etc)about 20-30k miles ago. I am worried about pump rub in xfer case. How much should I talk them to, so I get a good deal.
