No provision in a retail installment contract by which, in the absence of the buyer’s default, the holder may, arbitrarily and without reasonable cause, accelerate the maturity of any part or all of the time balance is enforceable. This section does not prohibit provisions in a retail installment contract accelerating any part or all of the time balance in the event of sale or transfer, or removal outside the state of the motor vehicle covered by the contract. [1957 c.625 §13]
