Display model Panasonic?

I was trying to buy a Panasonic P65VT50 at Best Buy and they were out of stock.
The manager offered me the display model for $1999.00. It was put up in Aug. of 2012 and he calculated it's been on about 1800 hrs. in "torch" mode.
It still looks great and from my reading, Panasonic claims a 100,000 hr. half-life on their plasmas.
It's fully covered by manufactures warranty and I could buy a Square Trade extended 4 yr from Costco for $99.

New ones are being closed out for about $2500. It saves about $500.
The salesperson said "on the plus side, no burn in issues and you can calibrate right away..."

What do you think?
Is it a good deal?
Thanks

Thanks for the feedback.
I asked about the service contract, but he was only willing to discount the price $100 (that would leave a cost of $250). He said that the corporate people are monitoring "add ons" and that with the price he gave me, he could only do so much explaining. From what I've read, the Square Trade warranty is a better deal for $99, although I'm open to opinions on this... Usually I just rely on a credit card to extend warranty by one year. However, this time I think it's wise to add more than one year of protection...
He did say that the TV is covered by full manufactures warranty and I have a 30 day return privilege, including home pick up. The issue is, that if a problem develops, I won't be able to get a 2012 model to replace it. They are all out of the 65" GT and VT series plasmas. That would mean stepping up to a 2013 model (at about $3k).
Does anyone have an opinion on the panel loss of brightness over time? From looking online, it seems that modern plasmas have minimal loss of "punch", but I'm putting it in a room with windows (which is why I wanted the VT) and it is a concern...
Thanks:)
