you do get some strange ones
the best one i had when i worked at VW was a guy who came in - smartly dressed and seemingly completely normal, asking about a cosmic green Beetle we had on our forecourt
I gave him the details on it and took him out on a test drive in it - it all started to go downhill when we got back and made him a coffee and talked about financing the car

He went on to tell us how he was a private detective and how he wanted something that wouldn't stand out - a lime green beetle

i'd manage to pass him on to the business manager who was stuck with him for hours
One of the service staff recognised him and apparently this wasn't the 1st time he'd been in with tall tails
Passed the time in the day tho hey
