Often, but not always - sometimes the benefits of scale are eaten up by an oligopoly gouging customers. In New Zealand, the big rental companies were much much more expensive than small local companies that were hard to find because they didn't show up on the international aggregators. And unlike the big companies, there were no hidden costs, no upsells, no attempts to scam, no attempts to extort huge fees when trying to change the rental, ... didn't even charge us for forwarding a traffic ticket which would have totally been their right. After my experience with Hertz (US) as a customer, the only reason why I'm not 100% happy with them going under is that I don't expect their large competitors to be much better, and less competition means the others can become even worse.
