Which small car is good for an 18 year old who has just passed their test?

My 18 year old twins have just passed their driving tests. Which small car is cheapest and safest?

Off the buses

My son aged 23 has just applied for his provisional driving licence and I am paying for some lessons as an Xmas present, as travelling to his new job by public transport is beset with problems. Any advice...

Do I have to tax and insure a vehicle if it's parked on a private drive and not being driven?

I bought a car privately - my first car. It's currently parked on a private drive and was delivered by the former owner who is sending off the appropriate V5C paperwork. Do I need to pay road tax and insurance...

Hyundai i10 (2008 - 2014)

Cheap to own. All models have airc on, five seatbelts and flat folding rear seats. Rides and handles quite well for its size. 99g/km Blue model from early 2011.

Kia Picanto (2004 - 2011)

Great value small car that is cheap to buy and run. Seven-year warranty on all new models from January 2010. Good rear passenger room. Much improved interior on facelifted cars from 2007.

Toyota Aygo (2005 - 2014)

Low road tax and insurance. Averages a claimed 60mpg. Cheap to run and drives decently. 99g/km CO2 from 2012.
