This might be a VX orientated forum, but you can do no better than looking at the Fiesta. The Corsa D was a pile.
If insurance is an issue, step up and look at the Astra or Focus - Both will be cheaper to Insure.
If image isn't a problem, go for a Hyundai i30.... not the best car to drive, but safe and reliable.
Consider others, like the Mitsubishi Colt and dare I say it, the Renault clit. Both nice things to drive (if you're into that type of thing).
Fiestas are slightly better cars than a Corsa, mainly because they are nicer to drive.
It's the other way round for the Astra/Focus. None of these four have any real issues.
clits are nasty flimsy things with a multitude of crap design issues.
Colts suffer from the traditional Mitsubishi problems; they were expensive to buy but feel cheap, they're not stunningly reliable and parts prices are comical until you actually have to pay for them.
Only speaking from personal experience, but the Fiesta beats the Corsa hands down. Better built, more reliable, quicker, safer and MUCH better to drive.
All the above applies to the Focus v's Astra (The Astra G was the last 'good' Astra). In fact, I retract my advice on lookin at a modern Astra - They are just as shit as the Corsa.
clit isn't as flimsy as you may think - My Mother had a 2006 model which served her very well - It's now in the hands of my Niece, and it serves her very well too. (Very thirsty for a 1.6 though).
Mitsi Colt, will last forever. No rust issues, no major mechanical issues and pattern parts are just as available as any other marque.
