 I have owned my Sequoia since new and have just rolled over 300,000 Miles!  This vehicle has been a real workhorse with 5 kids (4 girls - imagine the luggage) and numerous vacations.  It has never let us down!  The only mechanical issues I have had has been replacement of rear wheel seals twice and front ball joints (due to recall).  I can't say enough good things about this vehicle.  When clean, it still looks new inside and out.  I have never garage kept, but paint in excellent shape.  I have found that the rear door window is often faulty, but it is usually not the motor as you'll see on other posts.  About 200k miles ago, I put some dieelectric grease in the motor connector prob. solved.
