2015 Toyota Highlander SUV Limited Platinum 4dr SUV AWD (3.5L 6cyl 6A)
Why so scarce?
 Dealers do not seem to have a overabundance of the high end Highlander AWD limited platinum.  It was like pulling teeth to get a good discount on this model. Our local dealer had none and would offer no discount if he was to order one, tried to switch us over to a Rav 4! don't like to do it but had to travel to locate a dealer who would work with us and it still took over 3 weeks to come together and settle on a price.  I do not think you can turn down a price discounted 10 to 12% on the platinum model , that seems to be about as good as it gets.  Had it about three months and am quit satisfied with it, will see how it drives in the winter weather of Ohio.  Ordered the running boards, remote start ,side moldings and mat options , planning on keeping it for quite a while.  Only thing I don't like so far is as it downshifts back into 1 gear the engine revs a little high and the speed increases, torque converter does not seem to disengage during coasting to a stop.  Mirrors are a little too large. Mileage is now 14840 and it has been a yr. of ownership, and I still have no complaints other than the large mirrors . Holds the winter roads quite well, smooth and quiet, good on gas , Would buy again!
