...I actually have a bunch of hydrogas spares in my garage. Damn that fluid smells bad.
As the former owner of this MG Metro, I'll point out that its hydragas displacers don't really interchange with those used in anything else. This one is an early example, so its rear displacers didn't even interchange with those of the later Metros, although it's now running on the later units thanks to a customized set of shims.
The fluid smells okay-ish when fresh.
I would drive it myself. Not 100% sure I'd encourage someone else to do it, though.
In 2010 I drove this car from Seattle to Chicago and back, towing a French microcar on a trailer, so I'm happy to encourage anyone to do whatever fool thing they want with it. This was in the Wall Drug parking lot, Wall, SD, on the way there:
Does anyone have a spare seat where I could beebop along with the rally?
I may have a seat in my Volvo 66 GL, as it looks like my co-driver won't be able to make it. I should have a better idea within the next week or so. If the Volvo fails to make it to the starting line, as it did last year, I'll probably end up running the rally in my Austin Allegro 3 but would still have a seat if, as seems likely, my co-driver can't go.
