Three cars are included in the set. Two are missing figures and the yellow car is missing one wheel, both axles and the small silver metal piece underneath (see pic).
The wind-up mechanism works, albeit sometimes the tread needs a little "push" to get going. The rubber tread is in very good condition, free of any cracks or break.
We do NOT have a key, a borrowed one was used to test the wind-up function we used a generic key, you do not need an original key to operate. As with older, vintage toys, please be prepared for issues (mechanically, physically, etc) to arise. The set comes in the original box. The box shows some wear from shelf life/storage, but overall is sturdy and in good shape.
