2007 Nissan Armada LE

Does anyone own one of these? I'm debating on making a purchase. My local dealer has a 2007 Armada LE with about 89K miles, asking $16500. Looking for a family SUV. Looks to be in really great condition, even the leather is pristine. Its a V8 but was wondering how gas mileage really is and iv Nissans can be trusted beyond 100k miles? Anyone have any feedback that would be great.

Thanks
