Wanting a secure loan, Advice?

Ok so im thinking about applying for a loan for around �3000 to get a car ( i understand itl be a secure loan), i was wondering what chances i actually have of being accepted? i have been in my new employment for 6 months now and take home a decent wage. I have money spare each month and im currently working on paying of what debt i have (club-book etc only �800 balance left on �6000 limit) but have today seen a car ive fell in love with. I have other stuff out on credit in my name for my parents and haven't been refused anything since i apply ed for a car loan 3 years ago when i turned 18 stupidly, every things always paid on time from when i can remember but its normally min payment. Barclays gave me an overdraft and upgraded it just a few days later around month ago which they couldn't offer me 2 years back but i understand that a loan for this amount is totally different. i have brought a credit report for �2 but doesn't seem to tell me much i dint already know? and i cant actually see my credit rating. Does anybody know if its worthwhile me applying?
