I'm looking at a 96' Classic with a 3406E - 815,000 miles, 13 speed, 475 hp, anything in particular to look at?

VIN TP764567  I'm looking to see if its had any engine work. 

Also, why is Freightliner spelled the way it is?  What happened to the whole 'I before E except after C?'  The things I notice......

Thanks,

Marco
