I've previously shown photographs I took of various cars at the Footman James Classic Car Show at EventCity, Manchester in September 2016, and here are photographs I took of some of the Vauxhalls there.
This is a 1966 Vauxhall Viva HA 90 Deluxe, one of the first series of Vivas produced between 1963 and 1966 and powered by a 1,057cc 4-cylinder engine. It's the actual car depicted on the Wikipedia article about the Viva HA.
This is a 1964 Vauxhall Cresta PB with the 2,651cc straight-six engine that had been used in the PA. The PB was produced between 1962 and 1965, and from October 1964 had the larger 3.293cc engine and a full-width grille incorporating the headlights.
This is a 1971 Vauxhall Firenza, which was a derivation of the Vauxhall Viva. The Firenza was produced from 1971 to 1975 originally with a 1,159cc 4-cylinder engine, but this car has the 1,256cc engine introduced in December 1971.
This is another Vauxhall Viva, this time with an estate car body, and it appears to be the HC version produced between 1970 and 1979.
This appears to be one of the few Vauxhall Viva HBs to have been given the Brabham tuning modification, and the Wikepedia article about the Viva says this about them:
This time, apart from the standard and 90 stages of tune, there was also, for a brief time, a Brabham SL/90 HB that was purported to have been developed with the aid of world racing champion Jack Brabham. Brabham models were marked out externally by distinctive lateral black stripes at the front of the bonnet that curved down the wings and then headed back to end in a taper at the front doors. This model is almost impossible to find today. This model and the Viva GT are the two most sought after models made. The Brabham model differed from the standard Viva SL/90 in having a different cam-shaft, uprated suspension with anti-roll bars, different exhaust manifolds, and a unique twin-carb manifold, as well as differing interior trim. The Viva GT had substantially different engine and running gear and interior from the standard Viva HB models. It was distinguished by having a black bonnet with twin louvres and being all-over white. Later GTs came in different colours.
There may be some doubt about this car though, as this site seems to question whether TMD 179F is a genuine 'Brabham' conversion.
