hi
i had the same car - vauxhall corsa, y reg (6 months older than yours), space green 1.0i etc etc
mine was a club model which had a cd player, alloys, fog lights and only 46,000 miles on the clock. i part exchanged the car with vauxhall when i got my new corsa in january and they gave me 2200 for it. i thought this was a bit low as it was very clean in good nick etc etc, but considering you've got a lot more miles on the clock, 2 month MOT left and not much tax left, you might not get much for it because people wont pay a big price when they have to fork out tax and MOT. when i bought the car originally in july 05 they were asking for 3300 but it only had 2 months tax left on it so i offered 3000 to take the car the next day and get my own tax, which they accepted. i loved that car! i actually cried when i drove off in my new car leaving my old one there!!
good luck!!
