I have a 2 seater kid car for sale for £40. Its a dutch waterproof bike trailer for kids, id say to an age of about 5 each.
Its been used a bit and is still in good working order, could do with a little TLC and more use! My kids are now to big for it.
Its quite large so transport might have to be in a small van or trailer.
please PM me for more details and better photos!
its the same as the attached or the one in this link
