Ramp for my car (Seaside BN22)

If anyone has a ramp that I can put at the boot end of my car so I would be able to push my Bicycle into the back of my car & take it with me to places & when I get there get the Bike out again with the aid of a Ramp. If anyone has one they no longer need I'd love to have it & try out my theory, hoping that would work. Thanks in advance
