 I ALWAYS wanted one, so I took the plunge.  So far, the car has been a disappointment, but only due to small problems.  These issues have included interior leather defects, headliner replacement, some minor body damage noticed at purchase, and a popping noise resulting from servos that "click" on at 25-30 mph which activate the VDSC system.  This "click" sometimes feeds over into the audio system causing a "pop" in the speakers.  The "click" is normal, but the "pop" is not.  The dealer has been great with customer service and has always provided me with a vehicle while the Sequoia is in the shop.  Evidently, the '05s & '06s have had more complaints about "weird" noises than any year model.
