"Do you have it?" - and what happens when the answer is stale

The honest answer depends on where the data comes from

If the assistant reads a live feed from the stock system, it can say a vehicle is available and when that was last confirmed. If it reads a website page updated nightly, it must say so - "as listed this morning" - because the difference between those two sentences is the difference between a reliable dealership and one that wasted a buyer's Saturday. Ask any vendor exactly which source the answer comes from and how old it can be, and put the answer in the wording.

Never let it reserve, hold or promise

"I'll hold it for you" is a commitment no assistant can keep, because nothing stops a walk-in buying the same car an hour later. The configured behaviour is to confirm what the listing shows, offer an appointment, and state plainly that stock is not reserved until a person confirms it. A buyer told that honestly will still come in; a buyer who believed a car was held and finds it sold will tell everyone.

The near-miss is the opportunity most dealerships waste

When the exact car is gone, the useful reply is not an apology but the two closest alternatives in stock with the honest differences stated - older, different trim, higher mileage, different colour. Most buyers who asked about one specific vehicle will consider a close substitute if it arrives in the same breath as the bad news. Sent an hour later by email, almost none of them will.

Incoming stock is worth stating, with its uncertainty

A vehicle arriving next week is a real answer for a buyer who is not in a hurry, and most dealerships keep that information internal. State it with the uncertainty attached - expected, not guaranteed, and what happens if it slips - rather than either hiding it or treating it as available. A buyer who waits on an honest estimate is a buyer; a buyer who was promised a delivery date is a complaint.
