Are you sure you want to lease for 5 years? Most people lease for 2-3 years because they like to have newer vehicles often, but also because it is under warranty for the entire period. If you want the Tundra for that long, it might be worthwhile to just finance it. Toyota often times has really low APR specials for financing.
Hmmm… now that I think about it I don’t want to keep it that long. I will edit the terms.
