The story

Harris Mann drew a sleek wedge, but tall engines and a bulky heater made the finished car dumpy. It rode softly on Hydragas suspension and sold steadily, yet it became a national joke. The nickname was All-Aggro.

Inside

The famous Quartic steering wheel was a square with rounded corners, meant to give a clearer view of the dials. Buyers disliked it and it was dropped within two years. The posh Vanden Plas version had walnut picnic tables.

Figures here are for the 1500. Engines ran from 1.1 to 1.75 litres.

Meanwhile, in 1973

Britain joined the Common Market, and an oil crisis brought queues at the petrol pumps.

Buying and running

Before you buy a 1970s car

  • Rust is common in sills, wheel arches, front panels and the bottom of the doors.
  • Check the wiring and electrics carefully, as they age badly.
  • Many volume-selling cars still have good parts support, but badge-engineered and low-volume models can be harder to source.

General notes, not specific to this model. Check the model's own history before buying.
