Heysoos!
Mine was either the same as yours or white - no colour snaps exist - but it was the 1172cc side-valve engine.
This is my current ride today, in black, in my favourite weather; she's about eight years old but has less than 30,O000 klicks on the clock!
My two favourites? Humber Sceptre of 1974 with the black vinyl top, turquoise kinda colour; Fiat X1/9 from '79 in red, just before they introduced the Lido version.
The Humber was kinda suave, and the Fiat a poor man's Ferrari, which said it all.
