late model pu

I want to purchase a late model pu
that is good on gas and dependable.
I have found several models of toyota
sr series for sale.leaning towards a 4x4
with the 2.4 engine.
86 and 87 models with around 180k
extra cab or not?
Can someone please tell me the difference in those models and perhaps
the best bang for the buck.

What is a reasonable price to pay,as they
seem to go from high end to low.

Thanks in advance for any help,email me
direct if you like.

driven several older yotas... my personal favorite and the one i
currently owwn is a 1990 toyota 4x4 with a shortbed and a regular
cab... i get like 27-28mpg... and its been a dream... it has 170k on
it.... runs great
