Is this worth a lot of money? A nice wine for special occasions or is this a good bottle to break out for movie night?

I found one bottle for $45. http://www.cellaraiders.com/product_info.php?cPath=3_302&products_id=5001

However, Wine Spectator lists this year as past its peak. I say buy a back-up and pop it with some pasta. It scored well in 1986 (92 points), but it may not have much left at this point. Have fun! : )

What size bottle? A 1981 Inglenook Cabernet Sauvignon Estate Limited, Napa - 6 Liter bottle is currently going for about $800.00 (US)
