The Appeal

Alvis set out its stall with its first car, the 10/30: very well engineered and built to a high standard, these were high end and well regarded motor cars. The 12/40 evolved the idea with more power and improved gearbox and axle. 
Likely this 1923 12/40 is amongst the most unusual and well travelled of the handful of remaining examples. It was delivered as a chassis to Australia where it was fitted with a four seater body by Charles Kirkham of Petersham in Sydney. 
In 2000 it was acquired by an ex-Alvis draughtsman who commissioned the duck tail ‘super sports’ bodywork. This work was undertaken by a restorer in South Wales with additional work by other UK specialists. It returned to Australia in 2009 for further high-end work between 2011 and 2013. The car was back in Britain in 2015 before being purchased by a Dutch collector in 2020. 
Well known to the Alvis Register, this beautiful one-off Tourer is a very high quality vehicle in quite remarkable condition. For vintage collectors this is an exquisitely styled car in equally impression condition.

This impressive car with a remarkable history. An early 12/40 chassis, it was supplied new to the Charles Kirkham coachworks in Peterham, Sydney, Australia where it was fitted with a four seater body. 
By 1968 the car needed restoration. It moved around the country with different owners before being acquired from its third owner as a chassis in 2000 by UK-based Orchid Cars. It was then sold to an ex-Alvis employee, who had worked in the drawing office.  He commissioned a rebuild based around his design for a ‘super sports’ style duck tail aluminium body. 
This work was undertaken by a specialist in South Wales. It then passed to John Selway of Gainsborough who fitted new wings, hood frame, screen and retrimmed Sage Green interior. At this point the car gained its distinctive bright green wings and wheels and a double duck hood and tonneau. From there it moved to Early Engineering for mechanical work.
In 2009 the car was advertised by Early Engineering in the Alvis Register newsletter where it was spotted by its next owner. When he emigrated to Australia he took the Alvis with him. In 2011 specialist Tony Heard began a full rebuild which was completed in 2013. This work is accompanied in the history file by a detailed photographic record. 
The ex-Alvis employee re-purchased the car in 2015 and returned it to the UK. In 2020 it was acquired by a Dutch collector and has been carefully curated in the years since.

About Max Bids

The max bid process allows you to bid without any hassle.

Enter your maximum bid and we will then bid on your behalf to ensure you're the highest bidder - just enough to keep you in the lead and only up until your maximum.

Anti-sniping

Car & Classic prevent auction snipers from bidding in the last seconds to win an auction.

Auctions are extended by 3 minutes if anyone bids within the last 2 minutes to allow other bidders to react and counter-bid.

Auto-bidding increments

  • If your maximum bid is equal to or below the reserve price, your maximum bid will be applied in full if you are the highest bidder.
  • If you are the highest bidder and place a maximum bid above the reserve, we will automatically put in the reserve as your first bid.
    • Once the reserve has been met, Car & Classic will make sure you are the highest bidder using only the bidding increments stated below.
    • We will keep you in the lead up until your maximum bid OR the increment closest to your maximum bid, providing your maximum bid is enough to cover the increment value.

Bid Amount Increment
€0 to €9,999 €100.00
€10,000 to €49,999 €250.00
€50,000 to €99,999 €500.00
€100,000 + €1,000.00

Automatically outbid immediately

When you place a max bid and are outbid immediately that means that another bidder has placed a max bid limit which is higher than yours.

You can bid again and we will use our automatic bid system to try and get you as the highest bidder.

Matching max bids

When there are two max bids of the same value, the one placed first remains the lead bidder.

Pre-authorisation

We may hold a pre-authorisation charge on your card until the end of the auction when the hold will be cancelled. If you win, we'll take a security deposit which counts towards the payment for the vehicle and isn't any extra cost to you.

What are pre-bids?

A pre-bid means you're able to place a bid before the official start of the auction.
You will be notified whether or not you are the highest bidder when the auction starts.

Problem with your bid

Bids are contractually binding. To help protect you, we have some rules in place if we think it's been mistyped. Please check and amend what you have entered.
