The last HSV GTSR W1 Maloo ever built is up for sale, and it has never been registered.

Sydney classic car dealer Chrome Temple has been appointed to sell Walkinshaw build E005, the final of six W1-specification Maloo utes completed by Walkinshaw Performance. It has had one owner, is still on delivery kilometres and still wears its factory wrapping and stickers.

It's offered with price on application. Recent history suggests that price will start with a one.

The W1 recipe

The GTSR W1 was HSV's send-off as Australian Commodore production wound down in 2017. It ditched the GTSR's supercharged LSA for the hand-built 6.2-litre supercharged LS9 from the C6 Corvette ZR1.

That engine brought forged aluminium pistons, titanium conrods and inlet valves, dry-sump lubrication and a 2.3-litre supercharger. In HSV tune it made 474kW and 815Nm, making the W1 the most powerful production car HSV ever built.

The only gearbox was a close-ratio Tremec TR-6060 six-speed manual with a ZF Sachs twin-plate clutch.

HSV also swapped the GTSR's Magnetic Ride Control for fixed-rate SupaShock dampers, fitted AP Racing brakes with 410mm front rotors and six-piston monoblock calipers, and widened the front guards by 12mm each side with carbon-fibre vents.

The Maloo HSV never made

HSV looked at a W1 Maloo but walked away. Engineering and certifying such a tiny run didn't stack up, and LS9 engines were in short supply.

Walkinshaw Performance built them anyway, using GTSR Maloo donor vehicles, for a select few customers. Six were completed, numbered E000 to E005, and none were offered to the general public.

Walkinshaw has since moved out of the facility where the W1s were built, and the LS9 and W1-specific parts are no longer available, so there won't be any more.

Build E005

E005 started life as a Heron White 2017 HSV GTSR Maloo, HSV build #352, complied in April 2017. Walkinshaw finished it in 2023, and its paperwork records it as the last W1-specification HSV completed at the Walkinshaw facility.

It gets the full W1 mechanical package, W1 badging and a shadow chrome rear exhaust surround. Inside, it's trimmed in Jet Black and W1 Alcantara, with W1 embroidery, a W1 centre plaque and a W1 Maloo build plate in the door aperture.

VASS engineering approval certifies it as built to W1 specification. It also comes with:

• A Walkinshaw Certificate of Authentication signed by senior Walkinshaw executives
• Walkinshaw Performance build receipts and photos of the build
• Original vehicle documentation
• Two W1 keys
• A W1 Maloo car cover with its build number, E005

What have W1s sold for?

W1 Maloos are the most valuable road-going Holdens ever sold.

In December 2025, a never-registered W1 Maloo in XU3 Yellah with 26km on the clock sold through Lloyds Auctions for $1.2 million. The deal was done privately two days after the auction, and it's claimed to be the highest confirmed price paid for a road-going Holden.

That same yellow ute had been bid to $1.15 million at auction in September 2021 without selling, then was listed in the classifieds in January 2022 at $1.5 million.

Also in 2021, a red W1 Maloo sold at Lloyds Auctions for $1,050,000. A gold example reportedly changed hands privately for $1.15 million after a $1.05 million auction result.

W1 sedans go for much less, but still well over their sticker price. HSV charged $169,990 plus on-road costs for one new. In January 2024, a 32km 'Light My Fire' orange W1 sold through Collecting Cars for $350,888 hammer, or $362,888 with fees. Other recent online auction results have ranged from $157,000 to $340,000, and dealer listings have asked between $300,000 and $520,000.

So a delivery-kilometre Maloo with full Walkinshaw paperwork is likely to be priced in the same seven-figure range as those earlier utes. Chrome Temple hasn't published a price.
