I am looking at buying an 02 Grand Cherokee. The vehicle has 129K with a 4.7 V8 4x4 and appears to be in good running condition. Are there any major issues and/or problems that I should be looking for or can expect? If you own one would you recommend one?

The 4.7 is not very reliable,head gaskets and once in a while the valve seats come out of the cylinder head making the heads junk.Plus the 4.7 is expensive to repair if it breaks.A used 4.7 is not cheap,$1,500.00 for an used 4.7 out of an auto salvage yard.
