that's not a super rare model, 99% of all diesel pickups i see are '82-83 model 2wds with the L engine. in fact, i could've snagged a running L from a local wrecking yard for $200 a while back, but my old worn out 20R would've had no problem outrunning the thing.

if it's in immaculate shape, and taking the "rare" diesel into consideration, maybe $2k tops. $6500, he's dreaming. most of those trucks fetch $500, maybe $1000
