If you were any where near representative of the average customer you'd have an argument.
In the mom and pop segment, mom and pop don't like making excess technical choices. Most ppl have the 4 cylinder v. V6 concept already sorted out. The more frugal types, by their nature, have already decided on the 4 cylinder. "It will be good enough". Like a Motel 6; beats sleeping in the car outside of Edmonton in January.
Then go and pop 3 choices for that 4 cylinder and you've got a customer in termoil. What's best, what's the cost, what's the upside, what's the downside?
, .... to many whats! So the customer needs to think about it; do more research as they don't want to make a mistake. While thinking about they have now driven across the street to the Hyundai store or next door to the Toyota store where they find that decision has already been made for them.
