The early Skylarks should be looked at as a plaything - a good, cheap way of getting into the air and exploring your local area. It's not a serious cross country machine - Ka6's will eat it for breakfast, and rigging it is a team sport - also expect to have no friends when you land out as without good rigging aits it's hard work in a muddy field.
If you just want a toy, then it'll be fine. If you've aspirations of becoming a top cross country pilot, you'll outgrow it in very short order. It'll get around a 50k - on a good day - but you'll work hard for it. Can't remember much about cabin comfort but if other aircraft of that era that i've flown are anything to go by you'll hate it after 5hrs.
