Austin Morris 1100 - bought for about 100 if I remember at the end of my gap year working in oil services. Took it up to Uni - ran well, despite my sister trying to ruin the undersides by driving over a ten to twelve inch garden wall. The only issue was coming back from Uni at the end of the second year, laden down with my possessions and the gearbox stuck in third somewhere on the Scottish border with about 75 miles to go and Shap to take on.
