Apr.30 (GMM) The boss of the open wheeler series A1GP has lost interest in buying a formula one team.

South African millionaire Tony Teixeira enquired about the ailing Super Aguri as recently as ten days ago, but F1's clampdown on so-called 'customer cars' means that he is no longer on the market.

Teixeira last year was reported to be interested in Spyker (now Force India), Toro Rosso and Super Aguri.

"We wanted an A1 team in F1 where our winners would go and race in F1," he said in an interview with Reuters.

But Teixeira insists that with customer cars being phased out by the end of next year, he is no longer looking around.

"I sat with Toro Rosso and when we were close to a deal, F1 changed the rules: no customer cars. When they changed the rules, I was through," he said.

Teixeira insists that "there was no way we could go and develop our own chassis and be competitive".

"I don't profess to have that kind of money and even if I did I wouldn't put it into F1, it would be madness," he added.
