Passage Summary: It is cheaper to rent a car from a local dealer than a big national chain, but tourists have to pay for a taxi to get there and spend time finding them. Because of these extra costs and hassles, the author thinks locals get a better deal out of it than visitors do.

Conclusion: Renting from car dealerships is generally a better value for local residents than it is for tourists.

Reasoning: Although dealership rates are lower, tourists face additional hurdles like researching local availability and paying for expensive taxi rides from the airport to the dealership.

Analysis: The argument hinges on the idea that the 'hidden costs' for tourists (taxis and research time) cancel out the lower rental prices, whereas locals likely don't face those same burdens. To strengthen this, we want facts that make the dealership option even more annoying for tourists or even easier for locals. Since this is a 'Strengthen EXCEPT' question, we are looking for the one answer choice that either does nothing or actually makes the dealership option look better for the tourists. Keep an eye out for an answer that suggests tourists have an easy way to avoid those taxi fees or that locals have their own hidden costs.
