A lot of 2007/8 Vees are up for sale at dealers between £4,000 and 5,000 which makes yours in the ball park but as you're selling it privately perhaps it should be a bit lower. You're more likely to get nearer your price if you can hang on until spring when the weather breaks (hopefully), say April/May time which is when bikes sales start to pick up. You could buy a new Vee GT in 2009 for about £5,300 so used prices have held up quite well, mainly due to the increasing cost of new bikes. The new Vee being around £10,000. I very nearly bought a new Fireblade in 2002 for under £5,000, but rode one and found it rather dull! Currently selling for around £12,000.
