It's surprised me really, I had(my wife car) brand new 2000 VW Jetta, as I know it has worst reliability, and all them build in Mexico. I'm not saying other factories do better job. But I had 2002 VW Passat wagon, except water in the tank from bad gas station, I had zero issues. But I'm not sure where is built.Because they can't understand how a global company as big as Volkswagen works. They've also probably never seen how German plants are often full of former eastern block immigrants who hate each other and cannot speak the same language.
I have purchased 5 Volkswagens brand new... 3 from the Puebla Mexico plant, 1 from the Emden Germany plant, and one from the Wolfsburg plant. Want to guess which ones had the best build quality? All the Puebla cars. Not a single issue with any one of them. Nothing, nada. Nothing loose, no trim problems, no paint problems, nothing not lined up, not clipped in place properly, everything worked.
My Wolfsburg car had 3 assembly problems, 1 caught at PDI, the others remedied by me. Minor, but still there.
