I had LL924 and LL928. They were in the loft at my dads house so gave them to the kids who promptly took them to bits and they’re now “RIP” in the lego box, or rather reincarnated in something that’s a bit more of a DIY spaceship.
That’s what it’s for, though one day I might build 928 back up. I loved that thing.
I remember someone (who I think was a lego designer) built up a Lotus 340r. That was cool.
