friend had small shop and had many cars. he had early 90's chevy truck with a non-turbo diesel? or maybe it had a turbo but no intercooler? than a month later it was gone and he got a newer version with a nice shiny aftermarket intercooler. if customer did not want to fix vehicle, they sometimes sold them to friend for little to nothing. he had a 94 sts with a blown headgasket. for 1 month. used to bug me about my sts. his was $50 or something like that.
