Well if you track the SE region site with build and buy for zip 34423 you get lots of detail on model totals etc. I have been watching the numbers for about 5 months now. Sport and Limited are only about 2.5% each of total deliveries. V6 varies from about 10-16% of total deliveries.
But you can find them at local dealers but they go fast.
www.fitzmall.com always has a few at good prices.
And yes things come and go on the Toyota options list by region it seems.
The bottom line is they are selling all they can make and that is not a buyer's market even though I sense that prices are dropping some. Fitzmall has V6 for $200-500 over invoice recently down from $1000 over a week or so ago.
