I replaced my 2008 tacoma for an identical 2009 tacoma. 08 was NUMMI and 09 is Mexico. I have been doing research here and there because operations has always interested me. The Mexico plant has 800 workers and has quite a bit less automation when compared to the Freemont plant.
1 place where it is obvious that automation was not used is in the firewall seams.
Does anyones tacoma look like this under the hood. It appears that a sealer is brushed on. My 08 had a nice bead that looks like Johnny 5 put it on.
