My Son didn't get a lot part exchange when his Transporter blew up at 70k just outside the warranty period - they wanted nine grand to repair it. Utter Garbage.
How my Mrs laughed when her VW convertible locked itself with the engine running whilst she was scraping the windscreen.
How we giggled when the Polo went up in flames when the wiper motor caught fire.
How we enjoyed the dreadful gearbox in our VW UP and mpg nothing like the claimed figures.
How my Sons brand new GTI arrived with a respray

and what a pile of crap that's been for him.
How my camper van dropped a valve or when the solenoid stuck on the starter motor in Sweden

I think there were more.
Oh yes, the air cooled camper van that had the staff rolling around in stitches at the spares department. "Mate, I used to work for VW - that engine you've got in that was
so bad we used to tippex them when they went out and lay bets they wouldn't make their first service!"
