I usually choose a rental car based on where I plan to drive rather than simply picking the lowest price. For Mallorca, I can imagine spending one day visiting beaches and another exploring scenic roads through the countryside. A convertible could suit the first kind of trip particularly well. During my search, I found
https://roscarmallorca.com/convertible-car-rental-in-mallorca/, a page dedicated to convertible rentals on the island. I’d compare the vehicle specifications, luggage space, and rental terms before reserving one. There’s no point choosing a stylish car if it doesn’t fit the actual travel plans.
