Did I find a diamond in the rough?

Check it out what do you guys think for 14,500? If its not rusted out I think its a pretty good deal. Actual miles are 900k not 1.5mil like it says online. Just waiting on the seller to send pics of under the frame and the the cab mounts to make sure its not rusted. Deff looks like an o/o and not a company rig and it looks like the guy took pride in his ride

 

My dad knows that e7 inside and out and we have a local mack dealer 15mi up the road. We're going to ask for an oil sample, I just think it might be too good of a deal not to have anything wrong. It looks well taken care of though. We also have cash so im sure that 14.5 could be brought down to 12k cash in hand

 

No #### thank you good sir I'll run the vin threw our local mack dealer. Even if its not the original engine my dad can overhaul it himself for 5-6k

Im more concerned about rust

 

My dad wants to know if a mack dealer will be able to re flash it with the 460p settings? If under the cab and the cab mounts aren't rusted out my old man is gonna buy it. Suppose to send more detailed pics tomorrow. Last week we looked at 2 sister trucks that were boned out with only 500k. Good mech condition but just rusted beyond repair
