Used 100k Tacomas and 4Runners for teens is pretty much standard procedure around here, if the parents can find them and afford them.
My 2011 DC 4x4 V6 is a good truck. I wish Toyota would have put disc brakes on the back and a bit more agressive tune on the auto transmission, as it upshifts earlier than I'd like. With my 265/75r16 tires, I wind up locking OD out until I hit 50mph on a highway.
Always wondered why they didn't use Disc's in the rear, some on the toyota forums have put 4 runner discs on the rear and they were not pleased with the brake performance for whatever reason. I would like to know why they went away from a locking rear differential and now use ABS to control traction. That is Bullchitt, they alos neutered the Tundra that way as well.
