David Coulthard considered a testing role with Formula One champions Ferrari before securing a race drive with Red Bull Racing this year.
David Coulthard decided to sign for Red Bull for just one year
The Scot visited Ferrari last year as his stay with McLaren came to an end.
"I had the feeling that, if I had had the chance to work with that team, I would have felt at home," the Scot told Italy's Gazzetta dello Sport newspaper.
"We talked about the possibility of becoming a test driver. But, in the end, I had the chance to race."
The former Williams and McLaren driver had visited Maranello for the first time after asking if he could try out a Ferrari sportscar before a charity "race of champions" in Paris with seven-times world champion Schumacher.
"Ferrari are certainly a different team," said Coulthard, who finished runner-up to Michael Schumacher in the 2001 season with McLaren.
"Once I was at Maranello, I really felt the weight of history of that factory - of a team that has made and continues to make Formula One history."
Coulthard, winner of 13 races since his debut in 1994, signed for Red Bull in December after Austrian billionaire Dietrich Mateschitz bought Jaguar from Ford and renamed the team after his energy drink.
The Scot expected Ferrari, winners of 15 of the 18 races last year, to still be the team to beat.
He added that he had signed just a one-year contract with Red Bull because he thought that the most honest thing to do.
"If I find that I am still up to it and enjoying myself then fine," said Coulthard. "Otherwise, I will do something else.
"Above all, I still don't know what engine Red Bull will have in 2006, so it was premature to sign long-term."
