I did a lot of shopping. My wife's Hyundai Sonata was coming up on lease so I needed a replacement. She didn't mind taking my `03 Sport Trac (we still have with 225K miles on it, its like a Timex). I shopped for F150's but my folk's offered up the Expo. The price was way better, I knew the history/maintenance done, and my Dad takes real good care of his vehicles.
It also makes sense with 2 boys in baseball (8 & 12), me coaching, and all the crap we have to haul. Having the Expo everything is covered and locked up too. Plenty of room for vacations with the family and the dogs. Its worked out well so far other than the minor issues I've hit (AC/Heated Seats out, Alternator Pulley Bearing on its way out). From reviews I've read they ride better than the Tahoes, etc too. Not as powerful, but perfect for me. I don't commute far for work (14 miles one way) so gas mileage isn't a big deal.
