I'm not sure what's worse, actually. The fact that the cars were delivered with so many faults from the factory, the fact they they weren't picked up and rectified by the dealer during the PDI, or that many of the faults weren't simply properly fixed by the dealer - 4 attempts to fix a speedo cable pickup?
It's stuff like this that reassures me that my decision to buy second-hand and improve the car myself over the years has been a sound one.
