Fabulous quality VINTAGE MG - 2 1/2-litre OHC straight six cylinder engine. Robust, high quality upmarket MG, marketed alongside the sole other model, the MG Midget

Completely restored to the highest standards by the present owner - he acquired this most original example from the previous owner as a barn-find in 2002, having been owned by the single previous owner from 1955 - some 47 years standing in unmolested condition!

What better starting point to restore, than an untouched car, just 26 years old when put away in 1955...?

Please give me a call to discuss this interesting vintage MG

A car with a big attraction today when attempting to compare the MG 18-80 to almost any similar car make of the day - there really was nothing to compare it with - be it AC, Austin, Lagonda, Lea Francis, Riley, etc.,

The owner was intending to keep this car well into the future and had no plans to sell, - hence acquiring many spares along the way as insurance for the future - all spares - listed below - included in the sale...

The sole reason for the sale is that the owner has recently acquired another vintage car and so very reluctantly is offering this MG for sale - running out of storage space being the problem

There are circa thirty surviving Mk1 MG 18-80s. This car has had just on £9000 alone spent on the upholstery, carpets and new hood and side-screens; I can confirm that with the weather equipment in place the car is as water tight and cosy as a saloon.

The 18-80 is a very capable and confident car on the road with the torquey 2468cc Six Cylinder OHC twin SU engine. The smooth and quiet ride means it can cruise all day at 60mph making it an ideal long distance touring car. Indeed the owner has enjoyed continental holidays in company with a Speed Model example

Such was the fame of aviator Amy Johnson, as illustrated here – who flew on her solo flight in her de Havilland Gipsy Moth to Australia in 1929 – Sir William Morris - later Lord Nuffield - presented Amy Johnson with a brand new 1929 MG 18-80 Mk1 Saloon. The radiator mascot is a model of her Gipsy Moth – this mascot passing through the hands of the present owner of the MG I am offering here for sale!

As featured in The Autocar of 17th August 1928, prior to the 1928 Motor Show where the very first Six-Cylinder MG – the ‘MG Six’ - was first shown, “the latest model MG is an entire departure from previous practice in a very interesting manner –

Equipped with an overhead camshaft and valves, this smooth running new 6-cylinder 2468cc engine had an ‘immense crankshaft held by massive bearings in a cast-iron crankcase, the whole thing just about as stiff as can be imagined; stiffness in these parts is three-quarters of the modern six cylinder engine’ The Autocar went on to state.

Likewise the new sports chassis was designed for stiffness by a box girder frame and made as rigid as possible, preventing movement between components by not allowing the new chassis to ‘whip or flex’ as in the past. Indeed this attention to detail also reflected on the new design of braking mechanism – ‘every care has been taken to prevent lost motion and to make the brake pedal feel as though it were directly attached to the hub brake cams’ – so that foot pedal pressure immediately gave the driver the assurance that the brake pedal was more directly in touch with the brake shoe operation – also without the chassis whip causing any split second delay with the brakes taking effect. To enable more efficient braking, two large diameter brake cross tubes were employed, together with all the brake actuation levers being triangulated rather than by means of thin flexing stampings. ‘Of compensation there is none, the designers believing that the most effective form of brakes has the minimum number of parts, and an independent adjustment for each pair of shoes, as well as a single adjustment below the floorboards to take up all four sets of shoes simultaneously. Servo shoes are used for the front axle, the axle beam being really stiff and strong. Extra shoes in the rear drums are operated by the fly-off race-bred hand brake to the right of the driver.

On the dashboard is a 2-gallon emergency fuel tank, feeding by gravity when the main pumped tank is exhausted. In addition there is a similarly positioned oil tank for ease in the event of topping up the sump by gravity feed. Who else thought of that idea?

For extra ventilation the full-width opening windscreen hinges from the top, adjustable by clamping two rods either side of the screen.
