What is the AT Rating?
2 min read·Updated April 2026
The AT Rating is AutoTrader’s 1-100 score for how quickly and reliably a specific car typically sells. Higher is better — a high rating means the spec is in demand and moves off forecourts fast.
How it’s calculated
AutoTrader builds the rating from three signals for that exact spec:
- Market demand vs supply — how many buyers are searching, how much stock is listed.
- Recent sale frequency — how often the same spec has sold in the last few weeks.
- Days-on-market history — how long similar cars sat before selling.
The bands
- 80-100 — hot stock, usually sells in 2-3 weeks.
- 60-79 — average, 3-6 weeks typical.
- 40-59 — slow, 6+ weeks, may need price adjustments.
- Under 40 — hard sell, high days-to-sell, watch out.
How ScanAuctions shows it
We colour-code the rating in scan results so you can scan a column at a glance — green for 70 or above, red for 40 or below, neutral in between.
The AT Rating is only available when AutoTrader is connected. Cars valued by the Scan Auctions Valuation engine show no rating (—) since the score is AutoTrader’s own proprietary metric.
How to use it
When two cars in the same scan have similar profit, pick the higher-rated one — you flip it faster, which means less capital tied up and more turns per year. A £3,000 profit on a 90-rated car beats £3,500 on a 35-rated car nine times out of ten once you factor in holding costs.
Rating is a market signal, not a guarantee. Always sanity-check against your own forecourt history — some specs sell faster in your region than the national average suggests.
