Don't show eagerness or desperation and make it clear if you get a reasonable price of around 60K you would definitely consider.
Also, I can get you a 40D6600 3D LED LCD TV for around 84k. Best VFM I have seen is in 51D550 Plasma for 63K with 1 pair of 3D glasses which beats any LCD/LED TV hands down in terms of picture quality.
Well it's a 2010 model (going by the C), so chances are the dealer needs to offload the set more than you wanting to buy it. (unless he gets a clueless buyer)
You may also want to check the usage hours thru the service menu. Price can be brought down depending on how many hours the set has run.
for service menu: turn off tv, on your remote press Info, Menu, Mute and Power On to access Service Menu. (or turn off tv, press MUTE 1 8 2 then Power On)
I haven't, but tried. All the dealers I am in touch with have sold old models. And they keep cycling display pieces to ignorant customers so they never come down on pricing
