Can anyone help/advise?

[cuillich]

I've got one of the last (2013) c350 Coupes, AMG Sport Plus, Blue Efficiency (Petrol v6) with FMBSH, extended warranty, new MoT, new 'B' service etc. I'm vaguely thinking of selling it but not sure what the best thing to do/where to advertise/how to price it as a trade in will always be much to the dealers benefit.

Thanks in advance
