Doesn't sound too bad if your happy with the miles, afew more won't up it alot. Mines £350 but then I was only 22 when payed that and it was classed as my only vehicle, its been converted to diesel so marks the "modified" flag (gotta watch those 2.25d's, oh the power!).
I got unlimited mileage though as I can do 200 miles in a weekend, tried 4.5k and 6k in the past but kept exceeding it - give it a proper run!
