An AI assistant or an answering service for a dealership?

What each one is actually good at

An answering service takes a message in a human voice and reassures the caller. It does not know your stock, your finance terms or which model has a six-week lead time, so what it captures is a name and a callback request. An AI assistant answers from your own published material - specifications, terms, availability rules - and can therefore resolve the question rather than relay it. Neither can appraise a part-exchange or approve finance.

They fail in opposite directions

An answering service that does not know says so and takes a message: the failure is a delay. An assistant that does not know can either say so or invent something plausible, and the second failure is worse than a delay because the customer acts on it. This is the whole of the buying decision: an assistant is only worth more than a message service if it refuses to answer what it does not know.

Cost behaves differently, not just differently priced

An answering service is priced per call or per minute, so a busy month costs more and a launch weekend costs a lot more. An assistant is priced per period, so volume is free and a quiet month is wasted. The honest rule is that the answering service wins on low, unpredictable volume and the assistant wins once the same twenty questions arrive every week.

When the answering service is the right buy

If your evening enquiries are mostly people wanting a human, if your stock and terms are not written down anywhere, or if the volume is a handful a week, an answering service is the better purchase and an assistant will disappoint. An assistant needs published material to answer from; without it, it is an expensive way to take messages. Fixing the published material first is worth doing whichever you buy.
