I understand your worries Wayne. I felt very apprehensive before visiting my local vw dealership recently. My little girl has respiratory problems and i was VERY worried about passing on any infection. I decided to ring ahead and ask vw what precautions they had put in place. I was talked through how my visit would look from and was reassured to hear all they were doing (taking test drives alone, demonstrators wiped down after every use, hand gel in test car for me to use afterwards, one to one appts with a specific employee to limit contact with others etc). If you feel the need, I would suggest maybe having those conversations before your visits. It is daunting but I’m positive you will be fine, try not to let it overwhelm you and focus on that end goal!
Best of luck, happy motoring! ???
