Timo Glock on Wednesday said he would be "delighted" if he can race in the German touring car series DTM in 2013.
Having lost his Marussia seat to an as yet unknown pay-driver, the German - a former F1 test driver for BMW - quickly lined up a DTM test with the Bavarian marque.
The 30-year-old's debut was at Valencia on Wednesday.
"I saw his first lap and noticed that he was somewhat lost," Audi driver Mattias Ekstrom is quoted by Germany's Auto Motor und Sport.
"But when I saw him on the track later on, it looked as if he had found his way well. He looked quite happy."
Glock agreed with that assessment.
"As a formula one driver for a long time, it is obviously something completely different to suddenly have a roof over your head," he said.
"Luckily, I found the acclimatisation quite easy, and the same goes for the team, who gave me a warm welcome.
"I know many faces from the past, so I immediately felt at home.
"It was great fun," Glock continued. "But I also know that I have work to do in order to get a feel for how to get the most from a DTM car at the limit.
"For now we are doing this test, then we will see how we can take the next steps together. I certainly felt very comfortable right away and would be delighted if we could find common ground."
