I had one with 218k, dropped a bolt down the lower intake doing coil relocation (dumbass), and after getting all the way to taking the lower inatke off on a truck with 218k on it decided I was not going to put back together with old hg. I think @Best4x4 has the highest but then he bought his new and knew how to maintain them

 

Whelp, I was about to go over 200K, but she overheated and it ended up being a cracked block… But the old girl is about to be resurrected with a ~168K mile block. Transmission recently replaced, as well as virtually every cooling system component. So much aftermarket stuff that I can’t help but throw more money into the truck. Will trade for gently driven McLaren so I can break even!
