Id hold out for more, i hate selling its such a ball ache of a process but mine just went for 5k and was 77k on an 04 plate, also silver, couple of minor marks but other than that mint with a few tasteful mods. All about right person at the right time and its a good looking car so you should get what you want. Maybe its priced a bit too low, at 5750 people might think you want around 5500 just a thought.
