I'm impressed by the level of detail you've included, from the types of cars to the different packages available for monthly and yearly rentals. Sounds like Caryaati has something for everyone, whether they're tourists or locals.

That said, have you or anyone else reading this considered alternative modes of transport? While car rentals offer a lot of flexibility, they sometimes come with the hassle of paperwork, not to mention the driving experience in unfamiliar cities can be stressful. In such cases, a Private Shuttle Bus Service can be a good option. I recently learned about one in Aspen, and the convenience they offer is really hard to beat. No paperwork, no worries about parking, and the comfort level is high.
