Many of us here may say "absolutely!" but I guess that depends on what specific model it is. If it is an SWB (2-door, aka Short-Wheel-Based-model) the 89 SWB V6 is prized, particularly if has an auto tranny.

Besides, based on what you described as the problem, it may only be a blown head gasket. If you do the work yourself it's not that expensive to fix.
