I still have the truck I bought from Geoff (72WiscSub). More than 4yrs since I purchased it, still putting 5000-6000 miles/year on it. Finally wore out the tires, looking at wheel/tire combos (suggestions and pics welcome!).
I replaced the carb and have done some light mechanical work on it over the years, mostly just maintenance.
Even with all the miles and 3 big dogs the interior still looks fresh (smells mostly fresh, too
).
