Kia are owned by Hyundai and over the past few years have improved beyond measure in terms of design and quality. That said the Picanto isn't the latest in small cars and the Hyundai I10 is much more up to date click here Having driven a Hyundai Scoupe for 9 years and being well pleased with it, that's where my money would go if I was looking for something similar.
I would have bought one but the delivery time was way too long, so I bought a Skoda Fabia diesel instead, as they had one in stock. In truth the Fabia is a fantastic car, but is a bit dearer than both the Picanto & Panda.
Assuming your question was aimed at me, no, my daughter bought a 56 plate astra 1.4 five door. not what I would have recommended because of the restricted size of the rear hatch opening, but she seems happy with it. Havent had much feedback from her about it though.
Last year I bought a new 08 plate panda diesel for Mrs WTM. The dealers had a pile of them in and were knocking them out pretty sharpish at some good prices. £6700 got me a diesel with metallic paint (Herselfs choice) and aircon. I wanted a split rear seat but none were available in the right colour. Its a blast to drive, easy to park with the power steering set on city mode, cheap insurance (gp 2) £35 tax, 60 mpg round town, 68+ on a run. Boot isnt huge but handles a couple of banana boxes full of shopping with no trouble. Also got front electric windows, roof rails, remote central locking (big gripe: only get one remote keyfob, other is just a normal key) and mp3 compatable cd player.
