I'm looking at buying a 2004 expedition 74,000 miles. Are there any known problems for this year? Its has the 4.6L V8 SOHC 16V and the EDDIE BAUER package. 2WD

Ill be selling my 2005 Mercury mountaineer 120,000 miles

 

Other than being a bit underpowered for a 6,000 pound truck it should be ok for city driving. Just don't expect much when carrying a heavy load and NEVER try trailer towing with any weight or for a long distance.
You would be better off getting a good 5.4 powered A4WD that would do most anything for you and have some resale value when it's time to sell it.
