My wife has just passed her test and learnt in a Vauxhall Corsa (semi automatic). She liked driving the car but after some research I found out that the automatic gearbox on the Corsa is expensive to replace, problematic and not that reliable.

We dont want to spend much really as it'll be her first car. Can you recommend a good second hand automatic for around £2000 that has similar dimensions to the Vauxhall Corsa (approx 4000mm)?
