White 1971 Vauxhall Viva HC, not the one in the picture but identical to it, think it was 1156cc and reg was DUA 930K - ask me what my current car reg is and I have think about it!
Bought it in 1978 for £400 I think, I was living in York but going to college in South Shields. On one drive up to Shields I kept it flat out on the A19 - after many many many minutes it toped out 83mph!
Got to the college car park, looked under the bonnet to see my 'racing' had resulted in the head gasket starting to leak - bought a socket set, torque wrench and Haynes manual and did the head gasket in the college car park, first, but not last car repair I've done.
Car suffered terribly with tin worm.
Next car was a Mk 3 Cortina, followed by a Mk 4 both vastly superior to the Viva! - they were followed by a long list of cars, some good some not.
