Overview

We are delighted to offer this characterful and exceptionally well-documented 1973 Triumph Stag Mk II, presented in striking red with a beautifully preserved Chestnut interior, excellent folding soft top and just 48,341 miles indicated.

First registered on 25 September 1973, this particular Stag benefits from a remarkable history file spanning almost four decades, including an extensive collection of original invoices, restoration documentation and MOT certificates dating back to 1988.

The vehicle’s original factory commission plate survives and confirms its identity, original exterior colour, interior trim specification and manual-overdrive configuration.

Mechanically, the car benefits from a long-established Ford 3.0-litre V6 conversion dating back to 1988, together with a stainless steel exhaust system and extensive evidence of continued maintenance, including recent expenditure with Triumph specialists.

The car starts, runs and drives beautifully, while the interior has survived in particularly impressive condition.

Although further attention to areas of bodywork corrosion is required, this represents a thoroughly interesting and enjoyable classic with unusually comprehensive documentation.

Factory Identity and Original Specification

An important feature of this Stag is the survival of its original Triumph factory commission plate, which provides valuable confirmation of the car’s identity and original specification.

Commission Number: LD24552O

The commission number places the car within Triumph’s 1973 Mk II production sequence, specifically the third production series, commonly referred to as Sanction 3.

The factory identification establishes:* LD: Triumph Stag commission-number prefix for non-US Federal specification cars.* 24552: Individual commission sequence number within the 1973 Mk II production range.* O: Originally specified with manual transmission and overdrive.* Paint Code 72: Original factory finish of Pimento Red.* Trim Code 63: Original factory Chestnut interior trim.These original colour combinations are particularly attractive and complement the distinctive styling of the Stag beautifully.

Importantly, the commission number corresponds with the vehicle’s registration documentation, providing reassurance regarding its identity.

The original factory specification is further supported by published Triumph production records, which identify commission numbers LD20001 to LD25432 as belonging to the 1973 Mk II production series.

The car was first registered on 25 September 1973, making it an early example of the revised Mk II model.Exceptional History and Mileage Provenance

Without question, one of the most impressive features of ONV 222M is its extraordinary documentary history.The vehicle is accompanied by a substantial A4 lever-arch file containing decades of original invoices, servicing records, mechanical maintenance documentation and MOT certificates dating back to 1988.

This is far more than a handful of service receipts and provides a fascinating record of the car’s life.

The mileage is particularly well supported.

An engineering invoice dated 2 July 1988 records the mileage at just 28,615 miles.The subsequent DVSA MOT records demonstrate a consistent progression:

Current Reading48,341

The available online MOT mileages show no discrepancies, and the earlier paper records provide additional supporting evidence.

Remarkably, the car has covered just 5,312 indicated miles since its July 2006 MOT.

The mileage is described as indicated and supported by historical documentation, rather than independently guaranteed.

Documented 1988 Ford V6 Engine ConversionOne of the most interesting chapters in this Stag’s history dates back to July 1988.

An original invoice from Stewart Engineering of Chessington, Surrey, dated 2 July 1988, documents the installation of a Ford 3.0-litre V6 engine in place of the original Triumph V8.

The extensive engineering work recorded included:

Removal of the original engine and gearbox assembly.

Installation of the Ford 3.0-litre V6 engine.

Gearbox and overdrive-related work.

Replacement clutch assembly.

Associated mechanical modifications.

Stainless steel exhaust system.

Cooling system and ancillary work.

The odometer reading at the time was recorded as 28,615 miles.This is therefore a long-established conversion, forming part of the vehicle’s history for approximately 38 years.

The original invoice is retained within the accompanying history file, providing valuable supporting documentation.Documented Restoration – 1999 to 2007

The car underwent an extended programme of restoration between 1999 and 2007, with supporting paperwork retained.

This work forms an important part of its documented history and helps explain the attractive overall presentation of the vehicle, particularly the excellent interior and surviving trim.

Naturally, given that the restoration work was completed almost two decades ago, certain areas of the exterior bodywork now require further attention.

Mechanical Condition and Driving Experience

The car is a pleasure to drive.

Its Ford 3.0-litre V6 engine starts readily, runs smoothly and provides the distinctive soundtrack expected of a classic six-cylinder engine, complemented by the stainless steel exhaust system.

The Stag drives beautifully, offering a wonderfully engaging and relaxed grand touring experience.

The extensive maintenance history provides reassurance regarding the considerable mechanical attention the vehicle has received.

The vehicle passed its most recent MOT on 15 September 2026, at 48,306 miles, with the certificate valid until 14 September 2027.

Interior and Hood

The interior is undoubtedly one of the strongest aspects of this particular example.The original factory commission plate identifies Chestnut as the car’s specified interior colour, an attractive combination with its Pimento Red exterior.

The seats are in excellent condition and the dashboard and interior woodwork are particularly well preserved.

There is no cracking or deterioration to the dashboard or woodwork, which is especially pleasing to see in a vehicle now over 53 years old.

The interior presents exceptionally well and is a genuine highlight of the car.

The folding soft top is also in excellent condition.

No removable hardtop is included.

Bodywork and Areas Requiring AttentionWe believe in being completely transparent regarding the condition of our vehicles.

While this Stag presents attractively and drives beautifully, there are areas of corrosion around the wheel arches, sills and lower body sections, together with some localised paint deterioration, bubbling and cracking.Certain areas will require metalwork and associated paint repairs.

The MOT history also documents previous structural corrosion, including a failure in September 2026 relating to the offside front body structure. The vehicle subsequently passed its MOT on 15 September 2026.The current MOT retains an advisory for corrosion to the nearside rear body structure, together with several mechanical advisories.

Consequently, the car is not being represented as a concours example or a recently completed restoration.

It is offered as a complete, running and enjoyable classic requiring further bodywork restoration.

Prospective purchasers are encouraged to inspect the underside and structural areas carefully.

Comprehensive photographs and walkaround videos clearly showing the areas requiring attention are available upon request.

SummaryONV 222M is a particularly interesting example of the much-loved Triumph Stag, combining attractive original factory colour specifications with remarkably comprehensive documentary history.

Its surviving commission plate confirms its 1973 Mk II identity, Pimento Red exterior, Chestnut interior specification and original manual-overdrive configuration.

The extensive history file is a genuine highlight, containing original documentation stretching back to 1988, including the Ford V6 conversion, restoration history, decades of MOT records and recent specialist mechanical invoices.

With just 48,341 miles indicated, an excellent interior, excellent folding soft top and beautiful driving characteristics, this Stag has much to offer an enthusiast.

The bodywork requires further restoration, but the vehicle’s mechanical performance, exceptional history and reassuring mileage provenance provide a compelling basis for future enjoyment and improvement.

A charming, historically interesting and exceptionally well-documented British classic, offered with an honest description of its condition.

Further photographs, walkaround videos and copies of the history documentation are available upon request.Viewing is welcome by prior appointment in Leicestershire.
