What you need is a KZ VII !
Vintage, 4 seats, tailwheel, easy to work on, well within budget
Unlike your regalar cub, it is rare enough to attract attention but is extremely well supported by the Danish LAA (which is organised around the KZ Club). It will get in and out of any field you can stick a Super Cub in, and with more load too.
There is only one in the UK, but the good news is that I have it for sale
