What's the best automatic car for a new driver?

My daughter has just passed her automatic test. With a budget of up to £8k what car is safest, cheapest to run/insure and most reliable?

Can I report a dealer for selling a car at a rip off price?

How much should I pay for a 2008 Kia Picanto automatic with 17,000 miles? I am being told that these are like gold dust and I fear people are willing to pay over the odds. One has just been sold by a garage...
