A closed car showroom is when buyers come by
Buying a car gets planned at the weekend. People compare, drive past three dealerships in an afternoon, park outside your used car forecourt on a Sunday at 4 pm. Your sales staff are not there, and that is normal.
In front of a saloon in the window, the question is never vague. The buyer wants the exact mileage, whether the cambelt has been done, whether the warranty covers the gearbox, whether they can test drive it on Tuesday. A sticker on the windscreen gives the price and the year. It does not answer the rest.
On Monday, the salesperson sometimes finds a voicemail, rarely more. The other buyers carried on with their rounds, and took their question to the competitor down the road.
