Markko Martin held off the threat of Carlos Sainz on the final day of the Acropolis Rally to clinch his first championship win.
Martin maintained his momentum to the finish
The 28-year-old Estonian and British co-driver Michael Park finished in four hours, 53 minutes, and 40.5 seconds in their Ford Focus.
"It feels really good to finally win a world championship rally," said Martin.
"It's especially good to do it with the Ford Focus. We always knew we had a car capable of winning and it was just a question of time."
Spain's Sainz, twice a world champion, finished 46 seconds behind Martin in Greece with his Citroen Xsara.
Norway's Petter Solberg, in a Subaru Impreza, won four of Sunday's six stages to finish third, just 6.7 seconds behind Sainz.
Solberg edged out Britain's Richard Burns suffered gear box problems
in his Peugeor 126 for several stages.
But the 2001 champion's fourth place was enough to keep him at the top of the overall standings.
Scotland's Colin McRae, a five-time Acropolis champion, failed to boost his position in the rankings, finishing in eighth place.
His Citroen Xsara developed electrical problems, slowing him down in the final stages.
Reigning champion Marcus Gronholm, who came to Greece second behind Burns, retired from the rally on Friday with mechanical failure.
The Acropolis Rally is the sixth out of 14 races that make up the World Rally Championship this year.
