As a new 80 owner and a mechanic for 20 years I must say the truck has been a stout reminder that people neglect cars especially older luxury cars.
And by neglect I mean not only lack of maintenance but a lack of quality of maintenance.
With this said I do love the truck, it's a big step up from my Cherokee, and there are many one owner or two owner trucks out there so be patient and don't be afraid of spending a little extra cash up front to save cash in the long run.
