The 911 gets most of the attention, but the Cayenne and Macan cover a genuinely different use case — a Porsche that works for airport transfers and villa access, not just a weekend drive. Both are listed here separately by intended use.
A 911 rental typically requires a longer minimum driving licence history than most other cars on this site (commonly two years or more) — this is set by the supplier's insurer, not negotiable per booking, so it's worth checking before you get attached to a specific listing.
