Looked at a 72 Blazer w/3 year old oil

[Desert Rat]

Im looking for a 4x4 as som may know preferably a 73 up,so i dont have to tach,tilt, and want to find goodies for it,otherwise if i wasnt addicted to 67-72's id only get the correct year but im afraid i wont want to smash and beat it as bad.anyhow back to the point i looked a a 72 Blazer this weekend that someone put a 400 in,and it was mickey moused the typical wire mess underdash from a idiot installing a aftermarket stereo with a razor blade,his teeth as strippers,and scotc tape instead of cutters,crimpers and butt connectors or sauderind and electrical tape,it has a tilt one plus,has the heavy duty style buckets for some reason the fat ones,had 3 Ralleys and 1 white spoke,typical rocker rust,but im trying to think need a desert rock,and trail climber NOT a show truck now.then he says it hasnt been drove a whole lot.he said so little that he hasnt changed the oil in 3 years,because it only has about 4 thousand on motor in that time,but he thinks its probably about time.im thinking of the hard crust in the bottom of the pan and the sludge that has run through the motor the 10 minutes i heard it run,are some people just complete morons?he was proud a claimed mechanic he put the motor in,and changed the intake by himself.with its busted window,rear hatch,the rust,the old oil,the 4spd,the in serious need of a wire harness,no gauges worked,welded on front push bumper and grille gaurd,and the ruined tailgate from drilling and welding flat bar to it to hold the missing spare,then i might give him the $1800 he wanted i offered $600 kinda pissed him off,i said ill make you a offer but dont want to insult you,he said go ahead.i figured id part it,but if in my possesion i know id end up sinking cash into it,to make it all right.probably end up with all cool stuff and not want to got possibly roll it or something.and have another project anyone got a unfunky 69-72 4x4 with a junk unfixable body i wont be tempted to fix or 4x4 burb,or 73 up(ten i wont be tempted to find the options and new parts for them are cheap hood $100,fenders$68,doors$129.
