Hello, Sis had a 1999 XJ (Cherokee Sport), black w/grey cloth interior, 171K, SelecTrac (NP242).
'Twas clean under hood due to replaced PCV system, oil pressure sensor and new hoses + coolant.
Recent VC gasket, alternator, A/C compressor, serp belt and tail gate cylinders.
Clean 'n clear trans, brake, diff and transfer case fluid.
Near perfect body. Listed for sale 2 days after Hurricane Sandy (possibly the problem).
Gas prices were higher then.
The phone didn't ring.
Sold it to friends for $3,000.
I think a Grand Cherokee (piggy, aged "mommy wagon" with legendary electrical weaknesses - and not really a "Jeep") could fetch less.
A lot will depend on your schedule and where Upstate you live. Kira
