I've had my Explorer Sport for several years & and now at 133k & several WI winters later its still running well. The alternator is the only significant part that's failed. Keep up with the regular maintenance & you shouldn't have problems. Perfect for driving around town & for hauling things. I'll probably be replacing this one with another '02 or '03 since those were the last years for the 2DR.
The 4WD is great in snow & off road situations.
Make the towing package a standard feature. Also the interior quality could be improved.
