Intimating that he will leave McLaren at the end of 2006, the 30-year-old Colombian mentioned the words 'Toyota', 'BMW' and 'Renault' when grilled by the 'Autosprint' magazine.
He insisted: ''If you look around there's nothing … but available seats (for 2007).''
But, with his ear to the rumor mill, Montoya admitted that he is not as hot a proposition as his highly sought-after teammate, Kimi Raikkonen, who on Thursday was seen at the wheel of a Hydrogen-powered Mercedes bus in Melbourne.
Juan acknowledged that the Finn simply looks like a quicker driver of Woking-built silver racers.
But, explaining the simple problem of a clashing style in the cockpit, he said: ''For me, it would be interesting to see what the situation would look like in a different car.''
Montoya added that he would like to have his team for 2007 decided by the end of this year.
03/29/06 McLaren driver Juan Pablo Montoya says that he is unable to make a decision on his Formula One future until teammate Kimi Raikkonen decides where he will race in 2007.
"I'm looking around like everyone else, but around you can't hear anything but talks of Raikkonen going to Ferrari," Montoya told Autosprint.
"Or there are people saying he wants Renault, or he wants BMW, et cetera. All you hear about is Kimi."
With world champion Fernando Alonso confirmed in the McLaren squad for next year, Montoya is likely to find himself surplus to requirements should Raikkonen decide he wants to stay with the Woking-based team, with team boss Ron Dennis making no secret of the fact he wants to keep the rapid Finn on the payroll.
"At the moment I'm concentrating more on this season, on the fact that I'm here at McLaren," said Montoya.
"I only try to do my job the best I can and, when the time will come, we'll take the best decision for myself," he said.
