McGeorge Toyota in Virginia was on the Edmunds list as charging $520. They e-mailed me with a figure of $595 + tax. I don't know if the price has simply gone up or if the TCH costs more. I've tried several times to get a quote from Mechanicsville Toyota (also on the Edmunds list). I have e-mailed and called and left a message. I've not heard back.

The $595 figure was the 7 year/75000 mile Toyota Platinum warranty.
