Triplex 10-20 Special

The two-door sports coupé that thought it was an MPV…

THE Triplex Ten Twenty Special was presented at the Geneva Motor Show in March 1977 to publicise the firm’s newly-developed type of Superlaminated windscreen. Based around an Alfa Romeo, the car featured wedgy 2-door coupé styling courtesy of Chris Humberstone, with a removable glass roof section for open-top motoring. The sharply-styled front incorporated the retractable headlights that were all-but de rigueur for 1970s exotica.

However, its most unusual feature was reserved for the interior, where six individual seats were laid out in a three-row hexagonal pattern, with the middle pair set further apart than those fore and aft.
