Frankly, we cannot expect these flying cars to be sold in mass market any time soon. However, there are few companies who are doing R&D on roadable aircrafts. Apart from Slovak firm AeroMobil's AeroMobil 3.0 prototype, Terrafugia is another company exploring this arena with their TF-X prototype.
There is no price information about AeroMobil 3.0, since it is a prototype. The specifications include a Rotax 912 engine, body made up of composite materials. It has a steel frame and carbon coating. Top speed on road is 160kmph and a range of 875kms as claimed by the company. Top speed of 200kmph and above is supported while flying. It has a range of 700kms while airborne. 2 people can travel in this flying car. AeroMobil 3.0 also incorporates new features like avionics, autopilot, parachute deployment.
