I've got a brand new Citroën DS3 1.6 DStyle+; and I'd encourage anyone else to do the exact same thing I did for a first car! (18+)
Get it on a PCP, try different dealerships for different deals; but I put £999 down, then it's £199/Month for 2 years. Cracking car with lots of kit, and my insurance was £1.6k!
