The assembly quaity and fit is 9 on a 10 scale, the quality of some psrts I am sadly to say its not up to par, some parts specially electronic ones made by Bosh or Magnetti are quite bad 6 on a 10, that itself its no VW fault (directly) but as a hole the NB assembly line is top notch (and now that the demand is not so strong they are made at 80% speed so that gives 20% extra time to spot any trouble.)
