The 2004 ford excursions are good vehicles and have some of the best features. The 2004 ford excursion has sizeable passenger and cargo capacity, remarkable towing ability, and diesel engine option. The only con that comes with it is that it has a poor fuel economy and high sticker price. You can check out http://www.kbb.com/ford/excursion/2004-ford-excursion/ for some of its reviews.
Diesels are very nice motors, very reliable.. but expensive for fuel now, less sulfates in gas, which has brought the prices up. Now, I'm very opinionated against Ford's. Dont like them, never have. Not reliable, costly to fix. Other people really like them. I'd op for a Toyota or Honda, or even a Chevy.
