I am 28 but only passed my test a year ago. I will be doing about 24k per year on the dual carriageway commute (30 miles each way). My budget is £6000 but could add a little for the right car. Was thinking of a diesel, Golf, Polo, Focus or Peugeot. Happy to look elsewhere as I work in Swindon. What could I get or should I look at a new Korean car? A low insurance group is important.
