My Opinion:
All-Trac is lame because toyota uses it on station wagons and mini vans as well.
Turbo is lame because it broadcasts what you are
Toyota should come off, so you can stay symetrical with the other badges off.
I'm all for putting a GT-Four badge on because to me, it then makes the car respectful.
TRD to me doesn't really fit on our cars, because we have less support from TRD then almost any other car they support (i.e Corolla's, Matrix, Scions etc.) So in my opinion I say "Fuck em"
Plus I think the car looks really clean with no badges.
