Hi tom
Here you have a some ideas
You can park this road-plane in the garage,and (you can) drive it to the nearest airfield. You can fly to you destination, land, and then drive off the track, along a path to your workplace, in the air. But you can't float on  in the water.A plane has a larger storage space and it has many more places for passengers than in the road ready plane
In a normal car more people can enter and they have more space for luggage than in the road ready plane
Its main strength is that two functions are performed and the main weakness is when it was is transformed ina car, it becomes heavier. more heaviest

I do not recommend the purchase, because you they could not travel with  family or any other company.
