Apr.8 (GMM) Super Aguri will miss yet another major formula one test next week.

Other teams are planning either three or four day schedules at the Circuit de Catalunya, prior to the Spanish grand prix at the same circuit towards the end of the month.

But after sitting out almost the entire winter pre-season with financial troubles, and now firmly occupying the back row of the grid, it emerges that the struggling Japanese team's problems are not yet over.

Much has been made about the sale of Aguri Suzuki's Leafield based squad to the Magma Group, but team driver Takuma Sato on Tuesday confirmed that the transaction has not yet gone through.

The 31-year-old revealed that the Honda-powered outfit will not test in Spain.

The lack of development of the 2008 car is being compounded at races, where a lack of money and spare parts means that action even in free practice for Sato and teammate Anthony Davidson is rare.

"The final agreement is not yet finished with Magma, but hopefully it will happen very soon, and then we can press the button to start development," Sato said.
