Ok guys, i know its an xj forum but im looking for some constructive input! My 2000 xj died. I gotta replace it but am not a good enough mechanic to buy another xj with 200,000 miles. Plus, i still have my 99 xj! So i am looking at 2 different 2005 grands. One with the 4.7 liter v8 and one with the 5.7 liter hemi. Both are in the 80,000 mile range and less than 10k. My question is does anyone know if wither engine is really more reliable than the other? Any major issues i should know about? Any input is GREATLY appreciated. I dont normally have or spend this kind of money on a vehicle so im kinda nervous!
