I suppose it could be down to luck at the end of the day? After my first bad experience with buying a "first batch" car (which incidentally was a first generation BMW Mini, riddled with build problems eg dodgy seat mechanism, faulty airbags, faulty tyre pressure sensors, faulty seat belt mechanism) I swore I would never make the same mistake & would wait a year after new model releases.
However 10 years later I've gone on to buy four other "first batch" cars (Ford Focus ST, BMW E92 335, Mitsubishi Evo VIII, VW Mk6 GTi)... firstly because I can't stand waiting for things & secondly there's something 'pleasing' about being one of the lucky first few. However out of the four only ONE has given me problems... What's worrying is that it was the Golf that's had the problems (new engine fitted due to faulty timing chain tensioner, missing door grommets, blanking plates).
I just hope its not a sign of things to come!!!
