Just info, there is a legal term for "reasonable time" when a contract is entered, (the deposit makes it a contract). If all concerned got together a lawyer to represent those that have put deposits down which indicates there is a contract to deliver in a reasonable time the item contracted to delivered. A lawyer can take to court and also file for loss of interest that the clients would have received and sue for the anguish caused by the unreasonable time period. The Lawyer may be willing to take as Fee the loss of interest and anguish suit filed. Something similar was and happened in Illinois on smaller sized semi-truck. Deposits were taken, after 5 years still no product, nor even a production start finish date given. Lawyer won without ever going to court and just filing and forwarding letters addressing his representing each as a client and an agreed amount anguish settlement.
