One weekend, believe it or not!
I had a few cars lined up on the VW network - first was a Pirelli 5-dr at Oxford VW - was ok, but too much money for a very basic, no option car, with a door lock that didn't work. Honestly - you'd think a car on the forecourt would be without fault...
I then had planned to see an ED30 at VW Milton Keynes, but that sold before I could see it. So after that I went on to my car at Cardiff VW.
Thought I'd made a huge mistake when I got there on the Saturday as the car wasn't anywhere to be seen on the forecourt. After confusing a few sales staff, they found it and advised it only came in on part-ex the Friday night before, and was in the car park out back! No prep had taken place, and was absolutely filthy.
Still, must have been about the fastest sale they've had on a used car. Think I fell on my feet - it was properly grubby and well used - but could see through that, but I now appreciate all the options it has, that I didn't realise at the time!
