I’d send an email to the dealer principal stating the mileage at collection and the evidence you took from the app that the car was in use by an employee prior to collection. It’s simply not acceptable to use a customers brand new car as a pool car prior to collection.
some of you may recall my earlier post regarding my delivery mileage - below is the reply I received from the managing director
"Many thanks for your email and I hope you are keeping well in these strange times.
As you can imagine my ability to fully investigate your email is restricted as many of my staff are on furlough , as is the case with Volkswagen headquarters staff.
What I can ascertain is that the vehicle arrived with us with 60+ miles on the clock and whilst what I am about to say is assumption , the vehicle did take longer than usual to arrive at Emden from the factory which may mean that it was a car pulled out of it’s slot for secondary quality control. I can assure you the vehicle was not used by my staff as a pool car or anything similar , we have plenty of cars in our own stock so no requirement there. We did carry out the manufacturer required PDI which requires a test drive but that is no more than 10 miles and I can only account for the additional few miles being moved from our group storage compound to site.
I hope the above gives you some reassurance and I wish you happy motoring and stay safe."
Although I am a little frustrated still, I don't really know what more I can do and the car seems ok (the most important thing) and I guess life is too short to keep pursuing it!
