I have sent some direct messages to those who raised queries on here.
Airplane is available.
To rent you need an FAA PPL and a CFI check out in a PA28-181 (I am awaiting the insurance company to confirm that this can be done in UK before coming - they have ok'd for one, just double checking it applies to all) getting a CFI here can be difficult!
OK to fly it way for a week or so, nominally a 2 hour per day minimum; US$200 per Hobbs (wet - fuel here costs just under US$8/usg, away we reimburse at US$8), hull & liability covered for renters but there is a $5,000 excess (if you can get a renter policy to cover the excess it may be worth it - but needs to be US or UK as not for sale here).
Airplane has about 4,500 hours, 600 ish on the engine and had a six figure refurb five years ago (yes, the world's most expensive Archer II!), I fly it a couple of times a week.
