Best folding trike for two year old and up

[PensionPuzzle]

Looking at getting a folding trike (smartrike type of thing) for our two and a bit year old but a bit baffled by all the very samey looking options.

Essentially want it to fold up to take on car holidays (camping and center parcs kind of thing) and for walking to nursery for me to then carry on to work with to fold up out of the way until pick up time. She has a balance bike/scooter which she's starting to use, but I'm looking for the trike to bridge the gap between that and the pushchair as it's coming to the time to pass that on.

Looking at secondhand ideally so recommendations for older models are just as appreciated as newer ones 🙂
