The Appeal
The Alvis 12/50 hails from the pre-war era and gained popularity for its performance, reliability, and elegant design, becoming an icon of vintage motoring. Launched in 1923, it is now in its centenary year and what better way to join the celebrations than by having one of your very own?
This example has a storied history, wearing no fewer than four bodies during its life, and was well known in Alvis circles in the 1970’s, going by the name ‘Charlie Brown’, in reference to its period colour scheme. Featuring all of the desirable safety and reliability upgrades, it’s ready and eligible for a variety of vintage events.
Acquired by the current owner with the intention of adding to that history with some navigational rallies and hillclimbs, unexpected spinal surgery has unfortunately interrupted his plans. Hence it’s now reluctantly offered for auction and this is your chance to enjoy one of the seminal vintage Alvis models which is presented in fine fettle.
History and Paperwork
- Manufactured 1928
- Originally wearing a Carbodies beetle back body, research indicates that it was later fitted with a drophead coupe body and then during the war, it was converted to a pickup for carrying cement
- The current 2+2 touring aluminium and ash body was fitted by coachbuilders Jarvis around 50 years ago
- Previous owners had the car professionally maintained by Caleng Engineering who rebuilt the engine, fitted the gearbox with Register close ratio gears and upgraded the steering box with a new Register steering shaft
- Records with the car show that is was used for VSCC and Alvis Register events with a Prescott competition history that includes evidence of a time of 62.49 secs recorded in 1991 at VSCC Prescott

- Full flow oil filter conversion
- High torque starter motor
- Large bore Solex 40MOV sports model Carburettor

- Work in current ownership includes:
- Re-cored radiator (£1800)
- Accelerator pedal shaft rebushed

The Interior
- Front seats recovered
- Wood dash in good order
- Fire extinguisher
- Spacious and removable luggage trunk
With just one door - on the passenger side - to the benefit of rigidity, and usefully avoiding the spare wheel on the driver’s side, elegant entry to the car requires that you remember the correct angle of approach, lest you have to leap over the bodywork.
Once installed, you’re greeted with a wooden dash fitted with delightful instrumentation; the odometer font is a work of art in itself. The seller reports that all of the instruments and switches are fully operational, and even the clock keeps good time.
The front seats have been recovered in leather, show no signs of wear and are correspondingly comfortable. The rears, still in presumably original patinated leather, are likely to have seen little use as legroom is at something of a premium. They do however make for useful luggage space which is supplemented by the substantial trunk on the rear and numerous storage bins in the cabin - under the floor, beneath and behind the rear seats.
Modern conveniences include a hand held fire extinguisher, hidden USB charging point and battery isolation switch. The weather gear comprises a hood, sidescreens and a full tonneau and all are in excellent order, having been recently reproofed and waterproofed.
The Exterior
- Aluminium body with period brown paint
- Red painted spoked wheels
- Leather bonnet strap
- Hare mascot
- Very clean underside
While very presentable, this is clearly a car that has been enjoyed as the period brown paintwork bears the rubs, marks and scratches commensurate with over 50 years of use. That said, there are no significant scrapes or dents and, with the body being aluminium over a wood frame, no signs of corrosion to it.
The painted wheels also carry the marks of use but are not buckled, there are no loose spokes and they wear a matching set of good Firestone tyres in the correct size. The underside is notably clean with no obvious signs of corrosion and easy access to all of the major mechanical components, both from underneath and also via removable floor panels.
The overall effect is that it’s a charming and very usable vintage motor car.
The Mechanics
- Larger bore 1645cc engine with large port head
- Close ratio gearbox
- Stainless steel exhaust with aluminium Brooklands silencer and fishtail
- Spares package included
Thanks in part to the installation of a high torque starter motor, the engine fires immediately and, once warm, runs very well indeed without misfire or hesitation. On the road, it offers surprisingly nimble performance and is very capable of keeping up with modern traffic, happily cruising at 55-60mph on an A road. The recently overhauled brakes bring it up well and in a straight line.
Even over the archetypal British B road, there are no untoward noises from the suspension, while the fishtail exhaust provides an amusing soundtrack. The owner is not aware of any obvious fluid leaks and would be eagerly competing in navigational events were it not for his recent back surgery. Given its robustness, it would also seem eminently suitable for VSCC hill climb or trials events.
A small package of spares accompanies the car, including the original magneto and starter motors. Pictures of these can be seen in the gallery.
Summary
A thoroughly well sorted and nicely presented 12/50 that would be perfect for celebrating the model’s centenary year and will doubtless be enjoyed for years to come.
Jokingly referred to by the owner as a poor man’s 3 litre Bentley, we can’t help but think that whoever buys this will have their life made considerably richer for having it in the garage.

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.
