Mark Webber has no qualms about being handed teammate Sebastian Vettel's cast-off Red Bull to race in Sunday's British Grand Prix at Silverstone.

The 33-year-old Australian wrecked his previous car in a spectacular crash in Spain on June 27 when it rammed the rear of Heikki Kovalainen's Lotus before flying high into the air and crashing to the ground upside down.

The replacement is a chassis, dubbed 'Luscious Liz', that was rejected by Vettel in May after the German complained about its handling and swapped it for 'Randy Mandy'.

"There was nothing wrong with it. It's fine. It's all we've got anyway," Webber, who emerged unscathed from the crash other than a sore right big toe, said on a visit to the team's factory in central England on Wednesday.

The Australian revealed the car he shattered in Valencia had been given to him by the team weeks before the accident as a reward for driving it to victory in Spain and Monaco.

Rebuilt, it will be given back to him at the end of the season.

"I don't get attached to them (chassis) but clearly that one was unique," said Webber, currently fourth in the championship and 12 points behindd Vettel. "It did a great job for me.

"The boys put some messages on it because they thought it was RIP obviously, they thought it was all over," said Webber.

"Crunch (No 1mechanic Mark 'Crunch' Lenton) wrote in it 'You gave me the best day of my life, and also saved my mate.'

"The car's there to do a job and it did. It won races for me and looked after me when I needed it."
