Buying this 09 Cummmins ISX

[tree98]

Hard to tell anything from a video. How many miles/hours are on it? What truck is it in? What rear end ratio does it have? Has it ever been inframed or had anything major done to it? Is it deleted? Will they let you look at the abuse history using insite? Will they let you take the valve cover off to inspect the cams? A lot of information is needed to make an informed decision, but honestly if it has 500k or more on it it's highly likely it needs an inframe and probably a turbo if it's the original.
