This is what I paid.
I bought the DCab 5.7 C(package they call it)...navigation, backup camera, 20" rims, leather etc... for $49000 plus GST... I am not sure how great a deal this was. It also included side-bars and any other accessories I want at dealer cost (not sure how this one will work).
But, I still have to wait 1 month for my truck.
One thing that helped in my negotiations, was my willingness to shop elsewhere. When the sales manager heard me say I'd drive across the province to get the best price, he took a lot more than the original $1000 he offered off the MSRP.
One thing to add. Check out CarCostCanada.com for wholesale prices. This is where I gathered all my info on the Tundra prices before I negotiated a deal. It is a great site for those buying new vehicles.
