David CoulthardThirteen-time grand prix winner David Coulthard could be heading for a race seat in the DTM after sampling a Mercedes C-Class for the first time at Monteblanco in Spain last week.

The Formula 1 veteran, who has been a Mercedes roving ambassador, tested for two days alongside regular drivers Paul di Resta, Gary Paffett and Bruno Spengler. Mercedes is believed to be considering offering Coulthard a drive in the series in a 2008-spec car.

"The reason for the test was curiosity and fun," Coulthard told AUTOSPORT. "My relationship with [Mercedes Motorsport boss] Norbert Haug allowed it to happen. I've definitely got the taste for having another go, but it's too early to say."

Former grand prix winners Mika Hakkinen, Jean Alesi and Heinz-Harald Frentzen raced in the DTM after their F1 careers were over, while Ralf Schumacher is currently driving for Mercedes in the series.
