Paul I have not seen your car but it looks quality, I also am trying to sell some cars and the market seems really flat at the moment in the UK. I could have sold one for considerably more this time last year.
I have resorted to a Car Auction!
All I can suggest is get it posted on the web in as many places as possible to maximise the exposure. Motorbase, Classic Cars, Find It, Pistonheads, even if you dont think its the right place the more listings you get up there the more likeley someone searching the net will find it.
Good Luck
