Buyer’s notes
About the Porsche 911 SC
The SC replaced the 2.7 Carrera in 1978 and turned the 911 towards reliability. Its naturally aspirated 3.0-litre flat-six was markedly more durable than the 2.7 and did much to repair Porsche’s reputation for fragile engines. Every SC body was galvanised from new, and the Cabriolet joined the range in 1983.
What moves the price
- Body style: the SC Cabriolet, offered for 1983 only, is the scarce one.
- Colour: an original colour such as Guards Red sells faster and for more; silver, white and non-original resprays sit at the bottom.
- History: a documented, well-maintained car with a sound body, from a well-supported specialist network.
Before you buy, check
- That the hydraulic timing-chain tensioners have been replaced with the updated type, standard practice on any SC in regular use.
- The sills and floors: galvanising makes the body far more durable than earlier 911s, but not immune.
- The paint against the car’s original colour, as respraying in a different colour lowers the value.
