I'm 23 and have been saving for a while and am looking to buy my first relatively decent car (Previous cars were 2x Citroen ZX 1.4 1992 and 1997). I drive 13-15k miles per year and am looking for a sexy "low mileage" quick diesel hatchback that won't explode my insurance premium.
Have been mainly been looking for something like this: http://www.autotrader.co.uk/classified/advert/201305046599321
But am looking to broaden my mind and look at other alternatives.
UPDATE:
I have read and taken upon all your advice and my search options have opened up a little
Diesel or Petrol.
Fairly quick but not so fast my insurance sky-rockets.
Hatchback preferably but will consider alternatives that aren't massive.
Looks awesome.
Can offer good MPG when driving with fuel economy in mind.
Can stretch past 8k budget if car is worth that bit extra.
Viewed a couple of the 3 door Astras today and I love the look of the car but the interior is extremely boring just like Ben_Cole said.
Rule one of fight club, never spend your own money on a Vauxhall.
