Searching for something that won't cost a fortune? Check out the economy car. This efficient small vehicle is the most popular sort of rental car in Hong Kong SAR (and a dream if you're on a tighter budget). Top up the tank on the cheap and you'll be zooming around cities like Hong Kong and Ngong Ping in no time.It's always a good idea to get out of the city, and if you do, you'll be richly rewarded. With bays, sandy shores, and rolling hills to discover, Hong Kong SAR knows how to do an exciting day trip. A larger vehicle like an SUV or a four-wheel drive will give you and the family more room to move for those longer drives.
