The only reason why they sell it at 1000 yen is that they found the original 3 car formation and placed a straight rail underneath to make it more presentable. Fair prices indeed, but it depends on the train you are buying. Wait till you visit this cupboard. LOL!
And if you are lucky, you can find the intermediate car of an old Plarail for only 50 yen.
