Thanks for the insight. I've driven MB vehicles assembled in the Philippines. It's easy to identify these vehicles because the seventh digit of the chassis number is a 5 instead of a 1 (or something like that). I believe the 5 means it was delivered 'knocked down.' I believe there are several assembly sites in SE Asia.
How do you know 400Es were assembled in Mexico? Is there port of entry information on the vehicle or accompanying paperwork? How much assembly was left to Mexico? I hope the engines and transmissions were built in Germany.
