There wasn't much to go wrong with these things and they have a devoted following, so you'll have no problem finding Cherokees with better than 200,000 miles.
While there was an AMC four-cylinder engine and a GM V6 available— in theory— for the XJ Cherokee, just about every one I see has AMC straight-six power, either the 258-cubic-inch version of AMC Pacer fame or the later 4.0-liter type. This engine family goes back to 1964 and remains one of the all-time legends of Detroit (well, Kenosha) powerplants. In 1988, the 4.0 was rated at 177 horsepower and 224 lb-ft.
This one has four-wheel-drive and the oddball Peugeot 5-speed manual transmission.
The Cherokee came in a bewildering array of trim levels over the decades. The Pioneer was a slightly upscale version, with plaid upholstery and a standard AM radio (hey, factory AM radios were still quite expensive during the 1980s).
This one has some rust and a beat-up interior; truck shoppers around here can choose from plenty of cleaner Cherokees with three-digit price tags, so the crusher will be its next stop.
More power than the competition. A lot more power!
