Vettel eyes BMW or STR seat
The 20-year-old is more strongly linked with a two-season 'loan' move to Toro Rosso, but Robert Kubica's likely continuing teammate Nick Heidfeld is yet to pen an actual deal for 2008.
German Vettel told the news agency Sport-Informations-Dienst that he would "gladly" race for the Hinwil based squad, as he did in injured Kubica's place at Indianapolis, scoring a point on debut.
Vettel has been linked with BMW since 2004, when he became Formula BMW champion.
"So it is understandable that I would like to drive for them in formula one," he said.
He insists, however, that it is "too early" to talk about next year. "We will have to wait to see what happens with Nick and Robert."
Team boss Mario Theissen also does not want to be drawn on speculation about Vettel's future.
Referring to BMW's plans for 2008, he told Sport Bild: "There is no time pressure."
Theissen said there are "various options" for the Vettel situation, explaining that "we are currently evaluating these with Sebastian".
