Well, I have a 2003 Corsa which served me well and now up to 102000. Nice cheap car, insurance cheap too as it's only a 1.0 - won't get you much street cred though! Mine was fairly new when I got it, and I cared for it, unfortunately I get the feeling most of this era of Corsa have been trashed (engines going ka-boom due to timing chain fault isn't uncommon if they aren't serviced as needed!!)
Might be worth looking into though..my sister has the newer Corsa (an 07) - more on insurance due to engine size but a good little car.
p.s. Seems with little Vauxhalls/Fords etc. it luck of the draw weather you get a good one or not, but the good news is generally the stuff isn't too expensive when they do go wrong!!
