I've had this car for almost eight years. I have never, ever had a problem. I just take it in for regular oil changes and have done the 30K, 60K, and 90K maintenance. The only flaws in this car are cosmetic and were my own doing. I live in Oklahoma and have driven it to Las Vegas, New Orleans, the Texas coast, Rocky mountains in Colorado, and back and forth to Kansas hundreds of times. The fuel economy is reasonable given the size of the vehicle. I will have a hard time giving her up.
My 4Runner is purple and there is plenty of room for friends and/or stuff.
The only things I've ever thought to improve were minor and cosmetic and I can't even think of them right now.
