What the auction lot page says
What CarMargin AI flags
  1. 1
    HIGHCrash bar bent and corroded

    Needs replacing, not straightening. Check the mounts behind it on preview day.

  2. 2
    HIGHRadiator and condenser exposed

    No bumper in front of them. Look for leaks and bent fins before you trust Run and Drive.

  3. 3
    MEDIUMHeadlamp tabs likely snapped

    The lamp sits proud of the wing. Budget for a unit, not a repair kit.

Risks, high first
  • Subframe contactHigh

    Cat S with a destroyed wheel; the rails and subframe are not in any photo. Photo 10

  • Steering geometryHigh

    Expect alignment, maybe a lower arm and track rod after that wheel strike.

  • Radar calibrationMedium

    The forward radar sits behind the star badge; a new bumper means recalibration. Photo 9

Lot 48265746 · Bristol · 47,548 mi
BUY£3,903 max bid
Why this verdict?
BUY, because the damage stays on the offside front corner and the money works: at £3,903 you clear your 25% target with £2,400 set aside for repairs. Confidence is 72%, not higher, because there is no underside photo, so subframe contact is a read from the wheel damage, not a sighting.

What if I bid £4,800?
That is £897 over the max bid, and it leaves no room for the Cat S surprises: subframe contact, alignment and the radar recalibration behind the badge. I would walk at that number.

Anything in the MOT history?
The MOT history backs the mileage: 39,812 at the 2023 test, 44,105 in 2024 and 47,548 on the listing now. One advisory to note from 2024: slight play in the offside lower arm ball joint. The repair plan already replaces that arm.

All questions
Does it bid for me?

No. It never bids and never touches your Copart account. You decide, and you press the button.

Is CarMargin AI part of Copart?

No. CarMargin is an independent tool, not affiliated with, endorsed by or operated by Copart UK Ltd or any related company.

How long does an analysis take?

About 30 seconds from pressing Analyse. Most of that goes on the photos: every one of them, panel by panel.

What does it read?

The photos, the listing fields (category, mileage, damage, notes, highlights), the DVSA MOT history and the DVLA vehicle record. All four feed one analysis.

Do you keep the lot photos?

No. Photos are read in memory and discarded when the analysis returns. The image files are never stored and stay on Copart’s own servers.

Is the chat extra?

No. Chat is free on every plan, and it never counts towards your analyses.

Every lot on a trailer was somebody's max bid.

Make sure yours was the right one. Open any Copart UK lot, press Analyse, and get a verdict in about 30 seconds.
