According to reports from local press -not official statements- Whiting seems to have been favourably impressed with the general state of the Buenos Aires "Autódromo", saying that in its present condition it would automatically qualify as a Grade 3 and that with very minor alterations could make Grade 2, something which might be undertaken before the end of the year. Grade 1 could be attained quite easily at a cost that the local media quote at aroind 40M U$. He seems to have -surprisingly?- spoken favourably about the "loop around the lake" layout which was used by F1 in the 1974/81 period.
The obvious problem a possible F! comeback would face are the race fees. The new government is being moderately succesful in its efforts to turn over the economic crisis it inherited from the populist Kirchner administration but cash is still short and F! is not a priority on its spending list. Therefore, the cash would have to be put up by private investors but for the moment this seems to be a pipedream. Argetina doesn't have a Carlos Slim!
