It is going to depend upon the terms of the contract. Can the obligations of the contract be transferred? There is usually a transferrability clause in the contract that will tell you. If it says you cannot assign or transfer the rights, no, you will not be able to. If it is allowed, you may have to give proper notice and meet other requirements.
If the right to change the contract was in the original severance contract, yes. If not, no, a signed contract cannot be changed.

Can you change agreement to a mediation after you signed it? What is the grace period?
No. Once the severance agreement has been signed it becomes a legally binding contract.
A contract is a legally binding agreement between the parties who have signed it, unless written into the contract otherwise, all parties are bound by the terms of the agreement/contract they signed.
Once you and the dealer have signed the contract, it is a binding contract agreement and it responsible by law. You can take him to court if he doesn't keep his part of the agreement.

A properly written and executed agreement is called a contract. A contract that has been executed has been signed or possibly notarized.
A contract is valid when there is a meeting of the minds. Once a contract is signed, it cannot be changed unless written as an addendum and signed by all parties concerned. A verbal agreement cannot override a written agreement.
If there is no signed agreement then it is unenforceable as all of the terms relating to the contract are within this agreement.
The seller cannot change their mind once they have signed a contract unless there is some language in the contract that will allow them to back out of the sale. You need to review the terms of your purchase and sale agreement.
