Two decisions shape how a collision repair goes, and both get made in the first days of a claim: where the car is repaired, and what parts go into it. Neither decision is purely the insurer's, and neither is purely yours.
Who chooses the shop
Most states have anti-steering rules that prevent an insurer from requiring you to use a particular repair facility, and many require the insurer to disclose that any recommendation is optional. Legal surveys of the market count more than forty states with a statute or regulation on the point, though the wording and enforcement differ.
What an insurer can generally do is recommend a shop, describe the advantages of using one in its network, and limit what it pays to a reasonable amount for the necessary repair. What it generally cannot do is require a specific facility outright, or demand that you travel an unreasonable distance for an inspection.
Pressure that does not reflect the usual rules includes being told your chosen shop is "not approved", that repairs elsewhere carry no guarantee at all, or that the claim will be delayed if you do not use the recommended facility. If you hear any of that, your state's Department of Insurance is the place to check what applies and to file a complaint if needed.
Direct repair programs
A direct repair program, usually shortened to DRP, is a contractual arrangement between an insurer and a body shop. The shop agrees to pricing, procedures and cycle-time standards, and in exchange receives referrals.
| Using a network shop | Using your own shop | |
|---|---|---|
| Estimate and approval | Usually faster, since the shop can write and authorize within agreed limits | May require an insurer inspection or supplement approvals |
| Warranty | The insurer commonly warrants the workmanship alongside the shop | The shop's own warranty applies |
| Rental logistics | Often coordinated directly | You may coordinate more of it yourself |
| Parts | Program terms often specify parts usage | The estimate still governs what is paid |
| Alignment of interests | The shop has an ongoing relationship with the insurer | The shop's relationship is with you |
Neither choice is automatically better. Network shops are not inherently worse at repairs, and independent shops are not inherently more thorough. What matters is the shop's capability for your specific vehicle: certification for the make, the right equipment for its materials, and willingness to follow the manufacturer's repair procedures. That last item has become more consequential as vehicles have added sensors, cameras and structural adhesives that require specific procedures and recalibration. See safety technology, repair costs and your auto rate.
The three kinds of parts
Estimates use shorthand for parts categories, and it is worth being able to read it.
Original equipment manufacturer parts, written as OEM, are new parts made by or for the vehicle's manufacturer and sold through its network.
Aftermarket parts, sometimes called non-OEM or competitive parts, are new parts made by a company other than the vehicle manufacturer. Quality varies by manufacturer and by part, and some are certified by independent organizations that test fit and material.
Recycled, used or LKQ parts, where LKQ means like kind and quality, are original parts salvaged from other vehicles. For some components, particularly assemblies and body panels on older vehicles, a recycled original part can be the closest match available.
Reconditioned or remanufactured parts are used parts restored to a working standard, common for wheels, bumpers and certain mechanical assemblies.
What the policy actually promises
Personal auto policies commonly obligate the insurer to repair or replace with parts of like kind and quality, which is a standard rather than a brand requirement. Many policies also disclose explicitly that parts not made by the original manufacturer may be used.
State rules layer on top of that, and this is one of the more regulated corners of claim handling. Legal surveys count a majority of states with statutes or regulations addressing non-original parts in first-party claims. Common requirements include:
- A written disclosure on the estimate identifying which parts are not original equipment
- Identification of the part manufacturer in some states
- A like kind and quality standard, sometimes with a defined meaning
- Consent from the policyholder before non-original parts are used, in a smaller number of states
- Restrictions tied to vehicle age, with some states limiting non-original parts on newer vehicles
Because the requirements are genuinely state-specific and continue to change, confirm your own state's rules with its Department of Insurance rather than assuming.
If you want original equipment parts and the estimate does not include them
There are a few paths, and which is available depends on your state, your policy and the facts.
- Ask whether your state restricts non-original parts on a vehicle of your age.
- Ask whether an endorsement exists. Some insurers offer an original equipment parts endorsement that can be added at policy issuance for eligible vehicles. It has to be in place before the loss.
- Document a repair procedure requirement. Where the manufacturer's published procedure calls for a specific part or a specific process, that documentation is the strongest argument, particularly for structural components and anything tied to a safety system.
- Pay the difference. Many repairs proceed with the policyholder covering the gap between what the estimate allows and the original part.
- Escalate the valuation dispute if the disagreement is about the amount rather than coverage. See when you disagree with the adjuster.
If you are the injured party claiming against someone else's liability coverage, the measure is generally what it costs to make you whole rather than your own policy's parts language, which sometimes changes the conversation.
Supplements, teardown and the estimate that grows
An initial estimate is written from what is visible. Once the shop removes damaged panels, hidden damage frequently appears, and the shop submits a supplement for the additional work. This is normal and not a sign that something has gone wrong.
Practical implications:
- The first number is not the final number. Do not plan around it.
- Supplements take time to approve, which extends the repair and consumes rental reimbursement days.
- Ask about rental duration limits early. Rental coverage is usually capped by days and by a daily amount, and a long supplement cycle can exhaust it.
- Ask about calibration. Many vehicles need driver assistance systems recalibrated after a repair, and it is a separate line item that is sometimes missed.
After the repair
- Inspect before you accept the car. Check panel gaps, paint match in daylight, and that every warning light is out.
- Get the final invoice and the parts list, not just the estimate.
- Confirm the workmanship warranty and who stands behind it.
- Confirm any safety system recalibration was performed and documented.
- Consider whether value was lost despite a proper repair. See diminished value.
- Ask about your deductible. If another driver was at fault, your insurer may pursue reimbursement and return it. See subrogation and getting your deductible back.

Repair shop choice rules, parts disclosure and consent requirements, endorsement availability and claim handling standards vary by state, by insurer and by policy, and state law and your policy documents control. For your own situation, speak with a licensed agent, your insurer, or your state's Department of Insurance.
