Marcos 1500 GT (1966-67)

Overview: The **Marcos 1500 GT**, launched in **1966**, was a pivotal model for **Marcos Engineering Ltd**. It was introduced primarily to **reduce production costs** and streamline manufacturing after the **diminishing sales** of the Marcos 1800. By incorporating **Ford’s 1500 GT engine**, the company was able to offer a **lighter, more affordable** alternative while maintaining performance. 


One of the most significant changes was the **simplified wooden chassis**, which cut production time and costs. The **elliptical torsion boxes** replaced the **triangular chassis design** of the 1800, and the **front subframe** was redesigned for efficiency. Additionally, the **independent rear suspension** was dropped in favor of a **live axle**, further reducing complexity. 


Despite these cost-saving measures, the **Marcos 1500 GT retained the sleek body style** of its predecessor, making it a **popular choice** among enthusiasts. However, fewer than **100 units** were produced between **1966 and 1967**, making it a **rare and sought-after model** today. 

***** 


Production Total: The **Marcos 1500 GT** had a **production total of under 100 units** between **1966 and 1967**. This makes it a **rare and sought-after model** among classic car enthusiasts today. 

***** 


Price New: The **Marcos 1500 GT** was priced at **£1,195** when new in the UK in **1966**. This made it a more affordable alternative to the **Marcos 1800**, which had a higher production cost. 

***** 


Target Age Group: The **Marcos 1500 GT** was primarily targeted at **young driving enthusiasts** and **sports car lovers** in the **1960s**. It appealed to those who wanted a **lightweight, stylish, and affordable** performance car with a **distinctive design**. Given its **low-slung driving position** and **manual transmission**, it was best suited for **experienced drivers** who appreciated **precision handling** and **sporty performance**. 

***** 


Sales: The **Marcos 1500 GT** was a **moderate success**, but it didn't achieve **high sales numbers**. It was introduced in **1966** as a cost-effective alternative to the **Marcos 1800**, with a **lighter chassis** and a **Ford 1500 GT engine**. However, fewer than **100 units** were produced between **1966 and 1967**, making it a **rare model** today.


While it was well-received by enthusiasts, its **limited production run** meant it didn't have a major commercial impact. Marcos later introduced the **1650 model** in **1967**, which offered **more power** but still remained a niche vehicle.

***** 


Rivals: In **1966 UK**, the **Marcos 1500 GT** faced competition from several sports cars, each with varying price points:


- **Lotus Elan S2** – **£1,395**  

- **Triumph TR4A** – **£1,050**  

- **MG B GT** – **£998**  

- **Austin-Healey Sprite MkIII** – **£695**  

- **TVR Griffith 200** – **£1,750**  


The **Marcos 1500 GT**, priced at **£1,195**, positioned itself between the **MG B GT** and the **Lotus Elan S2**, offering a unique wooden chassis and lightweight design.

Recorded in UK 2025

There isn't a publicly available record of exactly how many **Marcos 1500 GT** cars remain in the UK in **2025**, but they are considered **rare**. Given that fewer than **100 units** were originally produced, the number still in existence is likely **very low**.

Marcos 1500 GT (1966-67)

COMMON FAULTS

Please Note: Common Faults in Regularly Used Vehicles vs. Low-Mileage Stored Vehicles that have been used consistently over many years, accumulating approximately 10,000–12,000 miles annually, are more prone to common faults due to regular wear and tear. These issues typically arise from the natural aging of components subjected to frequent use, such as engine parts, suspension systems, brakes, and tires. In contrast, vehicles with low mileage that have been stored or preserved are likely to experience different types of issues. These vehicles are often better maintained to ensure their longevity and may avoid some of the typical wear-and-tear problems seen in regularly driven cars. However, they can still face unique challenges such as degradation of rubber seals, corrosion from prolonged inactivity, or fuel system issues caused by old or stagnant fuel.


The **Marcos 1500 GT** had a few common faults, mostly related to its **wooden chassis** and **fiberglass body**:


- **Wooden Chassis Issues** – The bonded plywood chassis was lightweight but could suffer from **moisture damage**, leading to **delamination** or **rot** if not properly maintained.  

- **Fiberglass Body Cracks** – Stress fractures could develop in the fiberglass, especially around **door hinges** and **suspension mounting points**.  

- **Electrical Problems** – Like many British sports cars of the era, the wiring could be **unreliable**, leading to **intermittent faults** in lighting and instrumentation.  

- **Cooling System Weaknesses** – The **Ford 1500 GT engine** could experience **overheating**, particularly in **hot weather** or **heavy traffic**, due to **insufficient airflow**.  

- **Suspension Wear** – The **live rear axle** setup was simple but could suffer from **bushing wear**, affecting handling and ride quality.  


Proper maintenance and restoration can address most of these issues.
