Where our benchmarks come from.
AvantGarage does not own a price database. Reading a quote relies on public French surveys, cited with their scope. Anyone can check them.
What the service does
- Match each quote line to a known operation.
- Compare it with a public range.
- Classify the difference into four levels.
- Turn that difference into a question for the garage.
- Produce a PDF to share.
What it does not do
- No definitive diagnosis.
- No assessment of vehicle safety.
- No manufacturer labour times: this data belongs to professionally licensed databases.
- No account of the exact vehicle version or of the parts actually fitted.
- No judgement on whether an operation is technically relevant.
How a difference is calculated
- Each line's label is matched to an operation in the reference table below.
- Lines for the same operation are added together, because public ranges include parts and labour.
- The total is classified into four levels: below the range, within the range, above, marked difference.
- A marked difference starts beyond 30 % above the top of the range.
Operation amounts are compared including VAT, because public surveys are expressed that way. Hourly rates are given excluding VAT, as on a quote.

Our commitments
- No commercial tie with any garage and no commission on any repair.
- The quote you send is not shared with any garage or commercial partner. It is read by the analysis model provider, as described on the Privacy page.
- The method, thresholds and sources published here are exactly those the engine applies.
- A line with no public benchmark stays without a verdict rather than being filled with an invented estimate.
