I was thinking about picking up a MK6 about a year ago, test drove one and wasn't blown away with the engine. It felt like there was some turbo lag that was annoying so decided to wait and see if the MK7 would improve on this. I loved pretty much everything else about the MK6.
Fast forward to this year and I was able to check out the MK7 at the LA auto show and it completely met my expectations from a design and quality point of view. Obviously will have to wait for cars to arrive at dealers before any driving comparisons can be made.
All of this Mexico manufacturing nonsense is getting a little old. The current Jetta cannot be compared to the previous generation based on where it was manufactured. It is a completely redesigned car that was costed down for the American market. The same goes for the Passat. The only thing people have to worry about is the same problems that come up with any new generation of a car that are design related. Hopefully most of those issues will be resolved since the car has been in production for almost a year in Europe. There is a learning curve to assembling a product as complicated as a car is and some assembly mistakes can be made. However these same mistakes/overlooks can be made by Mexican factory workers or European ones. One would think that the quality systems that are setup in these facilities will catch 99.9% is these errors. I have been to factories all over the world, including Mexico, and seen how parts are made and products are assembled. There are always problems at the beginning of production. Once things stabilize in the production process there should be very little difference between European or Mexican made MK7s. I will also add that the majority of parts will be manufactured locally in Mexico, not shipped from Europe for assembly in Mexico. All new tooling will have been recreated at local Silao suppliers and there will be differences from parts in Europe. Any issues will be normal new production issues, not some substandard parts that some people are dreaming up.
Moral of the story. Mexican made MK7s will be have the same quality as German built ones after the normal production learning curve for a new car.
Along the same lines, BMW 3-series sold in the US are either from Germany or South Africa. Do you see BMW owners bitching about a quality difference between the 2 plants?
