Jan.18 (GMM) Timo Glock has revealed that he contemplated giving up his formula one dream after the setbacks of a few years ago.

The 25-year-old German made his grand prix debut towards the end of 2004, racing four times for Jordan before stepping back into the lower Champ Car and GP2 categories.

In the F1 support category in 2006 and 2007, however, he performed strongly, becoming BMW-Sauber's test driver in late 2006 and going on to win the GP2 crown last year.

For 2007, following a three-year absence from formula one, he has signed to race alongside Jarno Trulli at Toyota.

But he told the German newspaper Bild-Zeitung: "I did think about quitting."

Asked how he felt when Jordan did not offer him a contract to stay in formula one in 2005, Glock explained: "Well, I thought: that's it!"
