My Sail Car

I invented a car that works on electricity
It works well no complications sheer simplicity
Of course when it was ready to use oil price sank
It now cost only two thirds to fill up your tank
I think next-I shall put a sail on the car roof
Wait for a huge blast of wind and then –POOF
On my way I shall be with my car with the sail
That roams around on windstorm and gale
