I don't think they will give up the V8, else they will lose a large chunk of commercial user business.
I dearly enjoy seeing the dissing that goes on regarding OEM's building plants in MX. I have a 2013 Freightliner that this model was either built in MX or NC. My dealer was keeping his fingers crossed that mine would be built in MX, as they stated they have far fewer issues with the MX built ones. True to form, mine was built in NC and the dealer had to take two weeks to correct problems from the assembly. Some factory ordered stuff didn't even get installed! Just one of the many issues, only two of the 4 required brackets for the top air dam were installed and the air dam wasn't even included! Based on parts shipping delays that would have meant the two other brackets could not be delivered for several months, the dealer had to hand fabricate two more brackets. The air dam was located just 40 miles away at a YRC terminal, but they wouldn't release it because it was not set for delivery to the dealer for another 2 months per the factory! I told them I was jumping in my Jeep with a .45 auto and my Stoeger double barreled 12 gauge coach gun and I was going to retrieve my property being held hostage at YRC. Dealer called me back and said they told YRC the situation and YRC then released the air dam for delivery. So I am not all fired up with the anti MX crowd. Seems Pedro and Juan are very happy with the good paying job they have (in relation to the MX economy) than Bubba and Billy Bob are in NC, who seem to be more concerned with who is the latest chick at Hooters or where they are going bass fishing this weekend or who is playing Monday Night football.
