i have 105k now on my jeep. I haven't done any major repairs either, not that i could lol, mostly the basic maintenance and a few mods i've added to it for fun. Was talking to my dad last night about this, he's way more into mechanics than i am. He's adding new turbo and doodads to his Ram truck, 2500 turbo diesel , i think it's an '02 or '03, and he's been tinkering on his charger adding a few things. It's an '07. he didn't mention what he was doing on it. Guess he wants to surprise us next time we're there. He gets a kick out of modifying something then saying "hey you wanna drive the charger (or truck) up town with me?" lol
Anyway, from what he remembers on all the cars and trucks he's owned things were mostly imperial until about the mid 70's when they started importing more parts. His old Dodge '73 PowerWagon is a good mix of metric and imperial.
