Conventional automatics are less popular on modern cars as dual-clutch automatics tend to be more efficient, although there have been more reliability issues with these gearboxes as they age.

We would suggest looking at something like the Toyota Avensis, which is available with an economical diesel engine and an automatic gearbox. It also has good passenger space and an excellent boot, so you should find it fits your family well. It also has a good reliability record, and you should be able to find examples of this car from £5,000 upwards.
