Don’t know about you, but it feels like designers have less of a free reign with concepts than they used to. Modern concepts have to showcase advanced powertrains, lightweight eco credentials and the latest design language.

The concours d’elegance at the Goodwood Festival of Speed features some concepts which are a refreshing change from that. They’re cars from another era, built at a time when all they needed to do was grab some magazine covers.

As a result, they look like something from the Jetsons; you know they’re old, but they still look kind of futuristic.

Vauxhall said some of the design themes developed for the SRV concept of 1970 appeared on the Viva, but I can’t spot them. It was designed by Wayne Cherry as part of the American’s brief to shake up Vauxhall’s design. It featured gullwing doors with hidden door handles, self-levelling suspension and an adjustable aerofoil in the nose. Best of all was that the seats were fixed, but the controls adjust. Over-engineered? You betcha.

Far stranger and less attractive was the Bertone Lancia Sibilo. It was based on a Stratos chassis and dressed in bodywork that resembles a brown wedge of cheese. The glass is painted too, for additional brownness, while the steering wheel has a loudspeaker in the centre.
