The previous generation of (06-08) Golf stupidly called the Rabbit by the Herdon VA, Halfwits...is a great product...the newest generation of the Golf, now once again called err, the Golf is also fantastic ...ALSO MOST IMPORTANTLY FOR USA BUYERS IS THAT ACCORDING TO CONSUMER REPORTS THE GOLF IS AS RELIABLE OR BETTER THAN THE SIMILAR OFFERINGS FROM HONDA, TOYOTA OR MAZDA.....
I wouldn't hesistate to buy a NEW Golf gasoline or diesel....
Regarding build site location.....this WAS once a big problem back in the early to middle 90's VW was building the Golf and Jetta in Mexico and the quality was very poor compared to the German built cars...it was so bad that VWoA had to take every unit and put it through extensive quailty audit which resluted in quite a number of cars being extensively rebuilt....around the same time there was extensive labor unrest in Mexico as well so you can figure it out.
Today the Puebla MX plant builds a VW product that is equal to the German one due to better management, plant modernization and automation.
