“Looks like the Disney Land cruiser we were all transported in back in the 1980’s” is a strange sentence. Judging by the interior are y’all clocking this one at 53k miles or 153?
I don't see anything that obviously says it's 153k. There is one shot of the accelerator and brake pedals, and, while not the closest view of them you might like, they don't look worn at all. The interior does look very good. The engine compartment looks pretty clean, too, and it doesn't look like it had just been washed. There's enough of a light dust sheen that it probably looks in the photos like it always does. But, having said this, it could easily have 153k as well. He doesn't show the underside, and I would want to see that.
Based on the interior wear on our 114k mile 87 Pontiac (steering wheel, brake and gas petals) I believe the 53k mile claim is very likely true. In fact the lettering on the Chevy's dash controls looks brand new to me.
