Wow, man, if you would have said 5 years or so I would say go for the 68.
But if your going to keep it a long time............it would be a tough call for me. Nothing wrong with the 68. It's a really good tranny.............but......the Asian is a really really good tranny! See my point?
Kind of like I wanted a new BMW but could only afford an 06. Nothing wrong with my 06 Beemer, great car, its just I wanted a 2013 BMW!!
Don't let the 68 scare you off. Like I said, it's a good tranny. I'm sure you will be happy with either whatever you choose!! :)
