We bought our Explorer used from a dealer and have not had any problems. We currently have 72,000 miles on it and just love it. We upgraded the stereo with one that can play MP3's plus a 10-disc CD changer. The installer wired it incorrectly. The subwoofer is on the front channel, the middle speakers on the rear channel, and the front speakers on the center channel.
The 6-way adjustable leather seats are extremely comfortable.
With skyrocketing gas prices, we could use a few more miles to the gallon.
