3.0 liter SOHC longevity

Looking for a more fuel effecient vehicle than my 360 ramcharger.. and I see a million of the 3.0 liter cars around with high mileage... 200k+. Just wondering if say... a 93 stealth with a 5 speed and 215,000 original miles is worth buying in to for a commuter to work and back kinda vehicle? I have had a few of the mitsu 3.0 cars... daytona, lebaron..etc and they all had 150k ish and seemed fine, but never quite in the 200k area. How reliable are these motors at this mileage?
thanks,
Dave
