You and the other person you're talking about should go to the gym before the next event and man up then just lift it in and out of the boot

We just have a piece of MDF that we use to get Chimera into the boot, just drive him up it. Eric and Scar we just lift and we did the same with T-Bone from Jamie's car. I think we even lifted T-Bone down a 3ft drop rather than bring him down the driveway when we were doing that actually, dont know why, probably because it was about a 10ft shorter walk

And if you can get T-Bone into the back of a Skoda or Eric and Scar into the back of a Matiz then you'll manage to lift BB into a normal hatchback no bother.
