If an insurer prepares an estimate of the cost of automobile repairs, such estimate shall be in an amount for which it reasonably may be expected that the damage can be repaired satisfactorily.

36 OK 1250.8.H.
An insurer or its representative shall not require a claimant to obtain motor vehicle repairs at a specific repair facility. An insurer or its representative shall not require a claimant to obtain motor vehicle glass repair or replacement at a specific motor vehicle glass repair or replacement facility. An insurer shall fully and promptly pay for the cost of the motor vehicle repair services or products, less any applicable deductible amount payable according to the terms of the policy. The claimant shall be furnished an itemized priced statement of repairs by the repair facility at the time of acceptance of the repaired motor vehicle. Unless a cash settlement is made, if a claimant selects a motor vehicle repair or motor vehicle glass repair or replacement facility, the insurer shall provide payment to the facility or claimant based on a competitive price, as established by that insurer through market surveys or by the insured through competitive bids at the insured's option, to determine a fair and reasonable market price for similar services. Reasonable deviation from this market price is allowed based on the facts in each case.
