I have a 1997 Ford Taurus Wagon. While traveling I put a foam pad in the back with a couple of sheets and a light sleeping bag. In winter I use a couple of sleeping bags. There is still room for my guitar and a cooler. the suitcase fits under the deck. For attending the concerts with a gang of people I have seating for 7.

Good all round useful car. Haven't gotten laid in it yet though...
