First of all, there's a huge variety of both luxury and economy rental vehicles on offer in Diadema. What you go with is largely dependent on how much you're willing to spend as well as what you plan to do. Specialty vehicles are hard to beat if you're all about mod cons and comfort. If you feel like splashing out, why not book an SUV with all the bells and whistles, or perhaps a fancy medium-sized vehicle? On the other hand, if you're just after a car to get you around town as efficiently as possible, you're better off choosing an economy compact vehicle (or something else that won't burn a hole in your pocket).
