At Route 66 Auto Repair in Upland, CA, every repair starts with a written estimate you approve before work begins. If the problem is unknown, finding it takes testing, so we state the diagnostic fee at the counter first, and that fee applies to the approved related repair. Phone quotes are ranges until we see the car.
Is there a difference between a known job and an unknown problem?
Yes, and it changes how the estimate starts. If you already know the job, for example new tires or a scheduled fluid service, we can write an estimate from the vehicle details and a quick look.
If you only know the symptom, a noise, a warning light, a no-start, someone has to test the car to find the cause. That testing takes a technician's time and equipment, so it carries the diagnostic fee. A service writer states the fee before any testing, and if you approve the related repair, the fee applies to it.
How does an estimate get made?
Step 1: Tell us the symptom
When it happens, how long, and anything that changed. Your words go on the repair order.
Step 2: Fee stated, then testing
For unknown problems, the diagnostic fee is stated at the counter and testing begins only after you agree.
Step 3: Written estimate
We list parts and labor per line, with need-now or need-later labels and photos when the part is the point.
Step 4: Your approval
Nothing beyond the diagnosis happens until you say yes to specific lines.
Step 5: Stop and ask again
If the job grows once parts come off, we pause and contact you before going further.
Why can't you give an exact price over the phone?
Because we have not seen the car. A phone quote can only cover the likely case. Rust on a brake line, a seized bolt, a different engine option or a second failed part can all change the real number. So we give ranges on the phone and firm the price in writing after inspection.
A range is not a dodge. It is the honest version of a phone quote. Any shop that gives a firm number for a car it has not seen is either guessing or planning to adjust later.

Frequently asked questions
Do you charge for estimates?
If the job is known, such as tires or a scheduled service, we can write an estimate without testing. If the cause is unknown, finding it takes diagnostic time, so the diagnostic fee is stated first and applies to the approved related repair.
What do I pay for a diagnostic if I approve the repair?
The service writer states the diagnostic fee at the counter before testing. If you approve the related repair, the fee applies toward it. We do not publish an amount online because it depends on the vehicle and the system being tested.
Can you give me a written estimate before you start?
Yes, always. No work beyond the agreed diagnosis happens until you have a written estimate and approve it. If the job grows, we stop and ask again.
