Williams sells old F1 cars (FW28)?

[bosanac1]

I recently came across picture of FW28.

The owner posted that they bought it recently and its going up in their garage as show piece.

Is this show car replica or real Nico Rosberg FW28 ?

removed pic of owner for obvious reasons.

The front wing doesn't look like it fits the FW28, and for that year the livery was a lot different.
