like what Ghengis said........ there's a nice-looking Avid on fleabay, right now.
folding wings, trailer, water-cooled Rotax, ground-adjustable prop.....etc.
Take it home, bung it in the garage. realistically, 1 hour to reassemble and pre-flight once you get to your aerodrome.
all sounds good to me and would leave a healthy margin for 4-seater rental.
(and who's to say the rest of the family would want to accompany you?- been there with the boating job, good thing it was small/light enough for solo use! )
