well ya cant have a van if ya want 5 people in it so give up on that one...
ya could get a honda jazz, they hold alot as the seats go flat (so acts like a van when they are down), looks good i reckon and could get a decent 2003 second hand one for bout £6500 with 13000 on the clock and a 1.4 engine and they drive pretty well. just google honda jazz for reviews (they review pretty damn well) an go on autotrader.co.uk to see prices of them inthe area around you. not that dissimilar to a ford focus, but not sure if the seats drop flat like they do on the jazz (it is quite shockingly good, was surpised how much room there is when the seats are down)
The sun is shining the weather is sweet
