Mid-era
air-cooled 911s (1974-1989)
Galvanised
from the 1976 model year, but restricted by crude exhaust emissions
equipment. The 911 gems from the mid-1970s are the Carrera 3.0 and
the early 911SC. The Carrera 3.2 is the perfect starting point for
911 first ownership on a budget under £15,000.

Comments
These
models represent the truly affordable classic 911s, with the
3.0-litre ‘930’ block cars offering best reliability. Porsches
were fully zinc coated from the start of the 1976 model year and so
the later cars offer better longevity. That said, after 30 years, a good number of cars will be showing signs of rust,
particularly around the sills.
The Carrera
3.2s are divided by their gearbox type. The earlier models have the
classic Porsche 915 5-speed gearbox and these cars are generally a
little lighter. The 915 needs more skill to operate well. The later
models have the Getrag G50 5-speed gearbox and this offers a slicker
shift action. Many rush to buy the G50 gearbox car, but that
overlooks the top condition earlier cars. A good 915 car will serve
better than a bad G50 car.
The Club
Sport is the Carrera 3.2 many enthusiasts would love to own among
these cars. It has a blueprinted engine and many offer more power
than the stated 231bhp. They are also about 100kgs lighter than the
standard car. Take care not to fall for a fake though. Use a
buyers’ guide to spot the real ones from their chassis numbers.
The 930
Turbo started with 3-litres and progressed to 3.3-litres. The later
cars are much better, particularly as they have far better
brakes.
