2008 Toyota Sienna CE
 This van is well appointed even for the low end model.  However, at low speed, the transmission is very slow to shift with a rev that is unnerving.  The sliding doors just a few months after purchase have squeaked even though there have been several visits to the dealer.  I will be taking my van back to the shop again soon for this problem.  If the simple things not being done right bug you.  Avoid this vehicle until there is a major redesign.  Also there is the interior noise of the engine.  I thought I was driving a diesel.
