Would go and look at car. My wife was due to collect her new Mini , a few years ago, and was telephoned by dealer to cancel handover for a couple of days because of an update issue on the software. We never gave it a thought and took delivery a few days later. When selling the car ,three years later ,I got my local Chipsaway guy to sort out some stone chips pre sale. He asked if we knew the car had been partly re sprayed ! It was done very well and only a trained eye could see it. So your Golf may have had aknock in transit and is in body shop now . Go see. BTW , ever since, I have been interested in this pre delivery damage issue and have a client who actually repairs Volvos when they get damaged in transit, Last time I was in ,he had one of those new massive SUV things Volvo has just introduced ,with a crumpled roof ! He could repair it like new so owner would never know ! Lovely .
