I am looking into buying a 1988 Blazer K5 Silverado 6.2L diesel. It has 140,000 miles on it, with 6 previous owners. It came with all the options from the factory, and all electronics work. It is virtually rust-free except for on the tailgate, and the tires are in good shape. As far as I can tell, there are no problems with it, and it runs good. It has a very sparse history of repairs, and it is in original condition. You can see two pictures of it here: http://img176.imageshack.us/img176/1129/chevy1988nd6.jpg The asking price is $5,400 which to me seems a bit high, but maybe its relatively good condition warrants it? What do you think, would you pay that price for that car? If not, what do you think it's worth? Is there anything on this model year that sets it apart positively or negatively from the others? And how much more milage is it reasonable to expect to get out of the engine as it stands? Any comments and input would be welcome!
