The Citroen C3 Aircross replaced the Picasso and might be a good choice. The Flair model comes with speed sign recognition and rear parking sensors, and is available with a petrol engine and automatic gearbox as well as an opening sunroof. Also look at the Kia Venga. It's a similar size to the Picasso and is well equipped as standard - all models come with rear parking sensors and the top-spec '4' trim level comes with a (non-opening) panoramic sunroof.
