After competing and crashing in a disastrous Club rally, Rootes competition manager Mike Parkes encouraged Unett to attend a race meeting at the Goodwood Circuit, leading him to buy his first racing car,[5] a prototype from the Alpine development programme registration number XRW 302.

But Unett lost out on a major title, using his original Tiger as in the previous year, in the very last race of the Autosport 1966 championship.

[12][13] Continuing to race what were now highly developed Fraser Imps in 1967, Unett won the Grovewood 'Redex Gold Cross' championship.

[15] In 1968 the take over of Rootes by Chrysler, tougher competition and changes in the rules severely limited the Fraser Imp team's activities and success.

Unett already had a brief go at Formula 3 using a Lotus 31 in the 'Les Leston Championship' in 1967,[17] and he started to develop a Holbay powered car for Vixen.

Unett was a last-minute stand in for a three-man private entry for the 1970 London to Mexico World Cup Rally, using a Hillman Hunter.

The department had 'closed' shortly after their big win with the Hillman Hunter in the London to Sydney Marathon in 1968, due to Rootes' mounting losses.

O'Dell actually run it on a shoe-string budget relying on competition parts sales for finance until Works backing was reinstated in 1972.

[16] Also in this year, Unett entered a Hillman Hunter in the Avon/Motor magazine 2000 mile Tour of Britain, with Brian Coyle as co-driver, and finished First in class, 9th overall.

His biggest success came with the Hillman Avenger in the Rootes (later Chrysler) works Dealer Team managed by Des O'Dell, with which he won the 1974 British Saloon Car Championship season.

Unett won the 1600cc class on eight occasions, with victories at Brands Hatch, Mallory Park, Snetterton, the Thruxton Circuit and Ingliston.

[1] In 1975 Bernard Unett was elected to the British racing drivers club,[1] but the 1600cc Avenger was not competitive enough to get consistent results against the newly introduced Toyota Celica and finished up with only three class wins and out of the top three in the Saloon Car championship.

In the 1977 championship Unett won his class nine times against increasingly tough opposition from the Mini of Richard Longman.

A protracted dispute followed due to loose wording in the rules for point awarded for fastest lap, but after some weeks, Unett was declared champion for the third time.

Having been promised a Group 'B' car, in mid 1984 Unett took a squad of mechanics to Paris to work on the 205 turbo 16 set aside for the British rally dealer team.

The 205 Gti first competed in the 1985 'National Breakbown Rally', first leg of the 'RAC Open Championship', drivers being Louise Aitken-Walker and Mikael Sundstrom, but neither finished.

Unett was forced into retirement in 1988 when a back injury he suffered in a shunt ended his direct involvement in motorsport.
