Reading a G3 Remarketing catalogue

How to read a G3 Remarketing auction catalogue and its tick-list condition reports: the red crosses, the tyre table, the vendor surcharge that is not in the export, and how to set a top bid.

G3 Remarketing runs some of the busiest online sales in the north of England, and its catalogue is laid out differently from BCA's. The valuations are thinner, the condition reports are richer, and a couple of costs hide on the listing page rather than in the export. Here is how to read it so the car you bid on is the car that turns up.

The catalogue export

Each G3 sale can be downloaded as a spreadsheet: one row per lot with registration, make, model, derivative, mileage, colour, fuel, gearbox, grade and the vendor. What it does not usually carry is a full set of guide prices, so you cannot lean on a CAP column the way you might with BCA. That is not a weakness if you know your own numbers, because your own achieved prices are the better guide anyway.

The condition report

This is where G3 earns its keep. Every inspected lot has a tick-list report: a page of items each marked with a green tick or a red cross, a tyre table, and an inspector's comments box. Read it in this order:

  1. The red crosses. Each one is a fault the inspector saw. Warning lights, non-starters, damage and missing items all live here. Count them and price them before you look at anything else.
  2. The tyre table. Tread depth per corner in millimetres. Anything at or near 3 mm is a tyre you are buying. On a large SUV that is a three-figure bill per corner.
  3. The inspector's comments. Plain English about what the ticks and crosses cannot say: "intermittent fault", "smells of damp", "keys: one". This is the paragraph most buyers skip and most regret skipping.
  4. The grade. G3 grades run from 1 (best) downwards. Treat 3 and above as "price the work in" and read the report to see what the work is.
A cross you cannot read is not a tickIf the report image is unclear on an item, assume the worst until you have seen the car or spoken to G3. Silence in a condition report is never a pass.

The costs on the listing page, not in the file

Two things appear on the lot's web page and nowhere else:

Two quirks worth knowing

Setting a top bid from a G3 lot

Worked example

A 2017 Vauxhall Mokka, grade 4, 81,000 miles, two red crosses (one tyre at 2 mm, one warning light), vendor surcharge £85 plus VAT. Your last seventeen Mokkas at a similar age and mileage made a median of £4,000 and half of them sold inside 13 days.

  • Retail you can expect: £4,000
  • Fees and delivery: £600 · Surcharge: £102 · Tyre and diagnostic: £180
  • Margin you want on a two-week car: £700
  • Top bid: £4,000 − £600 − £102 − £180 − £700 = £2,418, so call it £2,400

A quick seller at the right money. The same car at £2,900 because "it's only a Mokka, they always go" makes nothing.

Doing this for a whole sale

A G3 sale can run to two or three hundred lots, each with a report to open. ForecourtIQ reads the catalogue export, attaches and reads the condition reports so the crosses, tread depths and comments are on the card, checks every registration with the DVSA, and scores each lot against your own sales. The surcharge is a tick on the card. The top bid is worked out from your figures, and the whole shortlist prints in lot order to take to the sale.

Questions dealers ask

Does the G3 catalogue export include guide prices?

Not a full set. Unlike a BCA sale report it usually carries no CAP or Glass's columns, so your own achieved prices for the model are the practical guide to what a lot will make.

What is the vendor surcharge on G3?

A fee some vendors add on top of the buyer's premium, quoted before VAT. It appears on the lot's listing page rather than in the export, so it has to be added per car when you work out a top bid.

How do I read the G3 condition report?

Count the red crosses first, then read the tyre table for any corner near 3 mm, then the inspector's comments. Price every one of those before you set a bid.

What do G3 grades mean?

Grade 1 is the best. From grade 3 upwards expect to price in repair or preparation work; the condition report tells you what the work is.

Can ForecourtIQ read G3 reports?

Yes. Attach the report to the lot and the crosses, tread depths and comments are read onto the card and priced into the margin.
