That my friend is a really cool out of the box idea, I love it!!
1- a vertical post built into the wall,
2- a manual slide out beam on a pivot
3- hook a winch to the post to lift the front of the car.
4-once lifted, insert a second pin 1" diameter or bigger, release and store the winch and down the road ya go! sweet!!
