Rent-a-Car is an online service for finding and booking self-drive car rentals in Istanbul, with options for pickup and return at Istanbul Airport. It brings together a broad selection of vehicles, with listings that include compact and mid-size cars, crossovers, minivans, convertibles, and luxury models. The service advertises more than 3,000 cars and lets customers compare available vehicles, prices, transmission types, and rental conditions before booking.

Search tools allow users to set travel dates and locations, filter by make, vehicle class, fuel type, insurance, deposit, payment method, and other requirements, and sort results by price or vehicle age. Listings show details such as model year, daily rate, mileage information, and whether a deposit is required. Some options feature no-deposit terms, cash payment, or different levels of insurance.

Customers can also look for extras including child seats, additional drivers, Wi-Fi devices, and winter equipment. Beyond Istanbul Airport, listed delivery locations include Sabiha Gokcen Airport and several Istanbul neighborhoods. The site also provides rental terms, FAQs, customer reviews, and travel guidance.
