You could get a fairly new low km '13 for what your budget is, definetely a '12. If that's the case and you do some looking and want newer, the 5.0 is a great choice. My personal experience with the two dozen '10's that I bought was limited to rear clutch packs and minor issues found straight across the board in every make and model. No issues with manifolds either. Regular maintenance and looking after your investment, I'm convinced it'll last longer. There will always be exceptions to the rule, but I can say that I have had good luck with both options.
