New, Unopened Sub-Zero 600 Series Refrigerator/Freezer
I have an opportunity to purchase a 600 series built-in SZ for about 1/2 the price of the current equivalent BI model. The seller is a local, bricks and mortar, authorized dealer that sells all the high-end UMRP appliances.
According to the seller, the unit is new and has never been open, displayed, used, etc., and I would get the full SZ warranty starting the day of purchase.
What do you think about this purchase? Is half off a good deal for an old model? Are there issues with the 600 series that I should be concerned about?
FWIW, if I don't buy this, I will most likely end up with a 30" Liebherr, so if you care to opine based on the alternative, that would be great.
Thanks as always for your help.
