This truck is approximately 6 inches long and is in nice used condition. I do not have the key for the wind up mechanism and as a result do not know if it works.  The spring is present and does not appear to broken, however, I can not be certain.  I ship within 2 business days of payment.  Shipping is free to the United States and Canada. I do accept returns in original condition within 30 days of your receipt of the toy truck with the buyer paying for return shipping.
