I know this post is OLD but I wanted to add something to this. I have also considered a 'new' taco and noticed the '05s were rated at 245hp 282torq (v6) while the '07 is rated at 236hp 266torq.
Basically why the difference? (maybe how they took the measurement)
Thanks in advance, I'm still using the 'search' function on here so please no flames.
