Chief Executive Ulrich Bez (pictured left) said AM hoped to complete a deal this year, but does not expect its Kuwaiti investor, Investment Dar, to sell its stake.
"Aston Martin is not a typical car company like General Motors or Peugeot. We are very sensitive or careful in looking for the right partner for the long term," Mr Bez said. "I can say there is a global interest which is not limited to the Middle East region."
Bez was in Dubai to boost the brand's image in the region.
Investment Dar said in December it was considering offers to sell up to 20 per cent of its stake in Aston Martin.
The Islamic investment firm bought a controlling stake in Aston Martin in 2007 from Ford for 479 million pounds (AU$994 million).
"Aston Martin is one of the most important assets in Investment Dar, therefore it is not about selling a stake but a question of how we can finance the growth in the future," Mr Bez said. "We are looking for capital to finance future projects."
Bez declined to identify the companies Aston Martin was in talks with, but said he hoped to seal a deal within the next three to six months.
