A number of earlier Kitfoxes are microlights. But that is pretty irrelevant as to quote one of my friends who built a VLA Mk2 (they can also be microlights) - 'it was the worst aircraft I have ever flown'.
For folding wings and non-permit - a few vintage DeHavilland types just about cover it.
But there is an interesting contrast in IMC flying and folding wings and keeping it in the garage - hence the paucity of types. Decent IMC performance typical needs a certain amount of weight - my own 560kg aircraft might be theoretically IMC capable but it would be very hard work. Folding wings on anything much over a ton and you're looking at aircraft which may be ex-Fleet Air Arm!
I have a friend with a Glastar - a pretty big 2 seater with folding wings - he has never used them 'in anger'. The idea of trailing the aircraft home is a theoretical possibility - which again has never happened.
