In search of something that won't hurt your hip pocket? Consider an economy car. This efficient small vehicle is the most popular sort of rental car in Serbia (and just the ticket if you're on a tight budget). Put gas in the tank on the cheap and you'll be easily zipping about cities like Belgrade and Pristina in no time.It's always a good idea to get out of the city for a bit, and if you do, you'll be handsomely rewarded. With rolling hills, mountains, and streams to discover, Serbia offers loads of day trip opportunities. A larger vehicle like a four-wheel drive or an SUV will give you and the gang more room for those longer scenic drives.
