My worst car - a Skoda Estelle. 5 Speed gear box, 1.2 litre engine. Should have been far better than the previous Estelle I reluctantly parted with doe to old age.

The "better" Estelle managed to die on me in the first week - the starter motor packed in, and the gear stick kept breaking its connection with the gear box, resulting in obvious problems.

I took it back (or rather limped it back) and demanded a better car, which I got.
