How market evidence becomes a valuation range.
Carvaly organizes Malaysian marketplace asking-price signals into decision-support ranges. This page explains the inputs, quality checks, confidence, freshness, and limits without publishing proprietary weights or thresholds.

1. Evidence used
A valuation starts with the latest completed snapshot of available Malaysian marketplace listing signals.
Carvaly primarily uses asking prices from active marketplace listings as market evidence. An asking price shows a seller's position; it is not a final negotiated transaction price.
Production market ingestion is scheduled every 14 days. A snapshot can lag changes made between ingestion runs, and coverage can change as sources, access rules, or data quality change. Carvaly is not a live census of every listing on the internet.
- Core vehicle details such as make, model, year, variant, transmission, mileage, and location where available.
- Asking price, observation time, and listing context needed to assess comparability.
- User-provided condition, history, and target-vehicle inputs when the valuation flow requests them.
2. Normalization and quality checks
Raw signals are standardized before any comparable group is used.
Make, model, variant, year, transmission, mileage, currency, and listing fields are standardized where the data supports it. Duplicate or repeated listings are reduced so one vehicle does not receive extra influence merely because it appears more than once.
Malformed, incomplete, or clearly implausible records may be excluded. Filtering reduces noise, but it cannot guarantee that every seller classified a vehicle correctly or that every marketplace field is accurate.
- Deduplication of signals that appear to represent the same vehicle and listing.
- Usability checks for essential fields and clearly mistyped or implausible asking prices.
- Exclusion of records that are not reliable enough to serve as comparable evidence.
3. How the range is built
Similar cars are assessed as a group; no single listing sets the value on its own.
Carvaly finds relevant make-and-model comparables, prioritizes the closest year and specification, then expands to adjacent years or trims when exact evidence is too thin. Variant similarity, transmission, mileage, and recency help determine how relevant each comparable is.
The cleaned asking-price distribution forms the market benchmark. From that evidence, Carvaly estimates a defensible band and relevant retail or trade context. Condition, service history, accident or flood history, and ownership inputs can move the read when the user supplies them.
- The closest matches are preferred before adjacent cohorts are considered.
- The comparable group—not one price—anchors the center and spread of the range.
- Exact weights, calibration, and thresholds are proprietary and can change as performance is tested.
4. Confidence and freshness
Confidence describes the strength of the available evidence; it is not an accuracy or sale-price guarantee.
The confidence signal considers comparable depth, similarity to the target car, recency, price spread, and how consistent the evidence group is. Many recent, closely matched comparables generally create a stronger signal than a small or mixed group.
When evidence is thin or inconsistent, a result should be treated as directional, may show a wider range or lower confidence, and in some cases Carvaly may decline to provide a range. Always read the latest completed snapshot time, comparable depth, and confidence together with the number.
- High confidence does not verify the physical condition or history of the vehicle.
- A saved result is a historical snapshot and may differ after a successful market refresh.
- Rare, imported, modified, or trim-poor segments usually carry more uncertainty.
5. Limits to understand
Carvaly is decision-support software, not an inspection, offer, or guarantee.
Carvaly does not inspect the car, certify mileage, verify title, clear finance, diagnose batteries or mechanical components, or confirm accident and flood history. Users remain responsible for appropriate physical, documentary, financial, legal, and identity checks.
Asking prices can be high, low, stale, promotional, duplicated, or unrelated to the final transaction. A valuation range is not a guaranteed sale or purchase price, official appraisal, insurance value, finance approval, or financial, tax, investment, or legal advice.
- Actual condition, repairs, documents, warranty, and a specific buyer's demand can change the outcome.
- Marketplace coverage and classification quality are incomplete and can change without notice.
- Use professional judgment and independent checks for higher-stakes decisions.
6. Corrections and changes
Verifiable feedback helps us correct public data and explain methodology changes.
To report a possible error, email support@carvaly.com with the page URL or valuation reference, relevant vehicle fields, what appears wrong, and supporting listings or documents we can review. Do not send payment-card details by email.
Carvaly checks corrections against the current data and logic. We update public wording when the evidence basis, operating schedule, or way users should interpret results changes materially. Historical results may be retained even when a later display or methodology changes.
- Include reproducible evidence and the date you observed it.
- A data correction does not guarantee a particular replacement value or transaction outcome.
- Material changes to this page will be explained in plain language without publishing proprietary controls.
