I think the Yeti or the A4 would be great cars, I doubt I would get a very recent A4 as they tend to hold there value, I wouldnt want a high mileage one with work possibly due, so it maybe a yeti which I think looks like a great car and I still remember the topgear review where Clarkson was driving through a building that was on fire and the climate control stopped his ice cream melting.
I see a lot of Nissan Jukes about I would say there one of the most popular cars round where I live any experience of them? are they particularly nippy etc.
The Citigo is on its way I have already ordered it 60bhp of raw sensible driving, its the family car I cant decide on, after working out our finances we can spend about 12k and it will be mainly used around town in the week and for trips out on the weekend so about 5,000 miles a year of use, im not keen on diesel as I had a Volvo that needed a DPF filter changing because it didnt get enough long journeys and the bill was nearly £2000!!!!
