Lift or mechanic's pit for new garage?

[Fuddyduddy1952]

As a kid one neighbor friend's Father made something interesting which was he used steel beams and poured concrete making ramps that went from ground level about 30+ feet long and up about 8 feet at the end where he had stops. It looked like it would hold a tank and it was very simple.
They used it all the time. It was outdoors near a shed.
