Your Rights at a Virginia Repair Shop: Estimates, the 10% Rule and Old Parts

Virginia has a specific law covering auto repair, and most drivers have never heard of it. Here is what any shop in the state owes you, including us.

A repair bill that comes in higher than you expected is one of the most common reasons people distrust mechanics. Virginia has an actual law about this, the Automobile Repair Facilities Act, and it applies to any business that fixes cars for profit in the Commonwealth. Here is what it says, in plain English.

You can ask for a written estimate

If a job may cost you more than $25, the shop must give you a written estimate on request, before work starts. It has to cover:

The estimated cost of labor
The estimated cost of parts
A description of the work
The estimated completion time

Two small details from the statute: a shop does not have to provide estimates before 10:00 a.m. or after 4:00 p.m. on a working day, and it does not have to give an estimate for work it is unwilling to do. The key words are "on request," so ask.

Nothing starts until you say so

Aside from the diagnostic work needed to prepare the estimate, repair work cannot begin until you have received the estimate and authorized the job.

The 10 percent rule

This is the part worth remembering. Once you have approved an estimate, the shop cannot charge more than 10 percent over it without your authorization. For a vehicle at least 25 model years old, the limit is 20 percent. Your authorization can be written or verbal, and the same rule applies if the shop wants more time than the estimate said.

So on a $600 estimate, the shop needs to call you before the bill goes past $660. When a repair uncovers something new, that is a legitimate reason for the call. A good shop will stop, show you and ask.

A shop can charge for the estimate

A shop may set reasonable conditions on estimates, including a reasonable fee for the estimate and related diagnostic work, as long as it tells you when you ask, in writing or on a sign posted at the entrance.

This surprises people, but it is fair. Finding an intermittent electrical fault can take a technician real time, and that time has value whether or not you buy the repair. The law only asks for the fee to be disclosed in advance, so there should be no surprises. A shop's own offers may go further. For example, we offer a free brake inspection.

You can have your old parts

When you authorize the work, the shop must offer to return the parts it replaces. There are exceptions for parts that have to go back to a manufacturer or distributor under a warranty, trade-in or core charge arrangement. If you want one of those, you may have to pay the core or trade-in fee. Even when a shop keeps a part for that reason, you can still inspect it.

Asking to see the old part is the simplest honesty check in car repair, and no good mechanic will be bothered by it.

You get an itemized invoice

When the job is done, including warranty work, you are entitled to a written invoice that:

Describes the work performed
States parts and labor charges separately
Distinguishes warranty parts from non-warranty parts
Identifies used, rebuilt or reconditioned parts

This does not apply to work done at an advertised single price, like a set-price oil change. Keep these invoices. They are your proof of maintenance if a warranty question comes up, as we explain in our guide to dealer and independent service.

Look for the "Customer Rights" sign

The law requires shops to post a sign headed "Customer Rights" that spells out your right to an estimate, the 10 percent limit, any estimate conditions, the offer to return parts and where to send complaints. If you are wondering what a particular shop's terms are, that sign is where to start.

What can you do if a shop ignores this?

Start with the shop. Most disputes come down to a misunderstanding, and a calm conversation with the manager, estimate in hand, often settles it. Put your complaint in writing if it does not.

If that goes nowhere, a violation of the Act is treated as a prohibited practice under the Virginia Consumer Protection Act. The statute directs complaints to the Division of Consumer Counsel in the Department of Law. Today, complaints go to the Consumer Protection Unit of the Virginia Attorney General's office. If you paid by card, your card issuer may also have a dispute process. For anything sizable, talk to a lawyer, since this article is general information and not legal advice.

What this does not cover

A shop that is honest about an estimate can still be wrong about a diagnosis. The law protects your right to information, not the quality of the opinion, so a second opinion is always reasonable on a big repair.
The estimate section does not apply to cars listed in the Antique Automobile Club of America's Official Judging Manual.
A shop is not liable for missing an estimated completion date because of an act of God, an unexpected shortage of parts or labor, or other causes beyond its control.

Five questions to ask any shop

Can I get that estimate in writing?
Is there a diagnostic fee, and does it go toward the repair?
Which items are urgent, and which can wait?
Will you call me before going over the estimate?
Can I see the old parts?

Those are good questions anywhere in Arlington. They are also the way we prefer to work: we explain what we found, quote it before we start and leave the decision to you. Our repairs come with a 1-year warranty on parts and labor, and customers who want to compare can read what our customers say.

Got an estimate from another shop that does not feel right? Bring it to 4035 Old Dominion Dr or call (703) 243-3080. We will look at the car and tell you straight.
