id pay a grand or under for a standard ke/ae depending on condition, MAX 1500 if it was straight and not rusty.
86, id pay about 2500 for a straight unrusty rolling shell with a 4ac to pull it around for a while.
for a ke with t series, lsd, 16v, all pretty tidy, one colour, straight, some wheels that are 14 x 6 or something, around 3500. if it had a 20v, 4000, if it had nice suspension, like all the 4 links, good coil overs, fresh brakes and what not, id pay 4500.
never really thought about an 86 so cant say what id pay for that,
rona, id pay 0-2k depending on condition, if it had a 3sge and suspension and decent diff, id pay 4500 if it was straight.
the thought of celicas and datsuns, mazdas very rarely cross my mind, except maybe a 929. or bow tie boot celica with a 3sgte, mmmmmm
