Buyer’s notes
About the Marcos Mantis
The Mantis M70 of 1970 was the only four-seat Marcos, a 2+2 grand tourer powered by Triumph’s 2.5-litre six, the engine of the TR6. Only 32 were built before Marcos ran into financial trouble and closed in 1971.
What moves the price
- Completeness: with only 32 built, missing trim and body parts are hard to replace.
- Condition of the body and structure, and the quality of any restoration.
- History: the car’s identity and its story since new.
Before you buy, check
- Identity: the chassis number against the owners’ club records, which keep the marque’s history.
- The Triumph six: oil pressure, smoke and leaks, and a specialist’s view of its fuel system.
- The body for crash repairs, cracks and poor paint, and the chassis for corrosion.
