Trading in shares of Spyker Cars on the Amsterdam Stock Exchange was suspended in advance of a pending announcement regarding Spyker’s attempt of buying off Saab. The stakes were frozen at €3.91, an 82% increase since trading ended last Friday.

Backed up by the Russian bank Convers Group, Spyker has been hammering a deal with General Motors to purchase Saab. The latest offer is believed to be valued at $550 million in cash and stock. Recent rumors also suggest that a Spyker vehicle has been delivered to the Saab museum in Sweden.

A source close to the deal said that the deal has almost been completed but the trading will be suspended until a statement is released to the media. Should the announcement confirm the sale, the Dutch automaker’s stock is expected to spike higher, despite Saab’s consistent losses.

However, if the deal collapses, Spyker’s share value could hit back to €1.71.
