First of all, there's a wide variety of both economy and luxury rentals in Sina. What you end up opting for depends on how much you want to spend and what you plan to do. Prestige vehicles often spare no expense when it comes to comfort and class. If you're splurging, why not book an SUV with all the bells and whistles, or perhaps a stylish mid-sized vehicle? Otherwise, if you just need a car to zip around town in as economically as possible, you're better off going with a budget compact vehicle (or something else that won't break the bank).
