What is the AT Rating?

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.

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.
