i reckon it's Tiff, he has a lot of history with Top Gear, i'd say it's him or else it's an ex F1 guy, Herbert or someone like that. The way he drives sometimes tho you'd think it was McRae, Stig's a legend.
thats right noel - the stig was origionaly perry mccarthy -he even had a book with perry mccarthy (the stig) on the front cover!
They supposedly changed the driver but its prob still him, I think tiff is contracted to channel 5 and fifth gear now - last episode i saw the were slagging top gears track so I doubt it if hes the stig!
the Stig changes, Mc Carthy was sacked cuz he couldnt shut his mouth that he was it.
Hekki Kovalinen has done it a few times, notably in the Reno F1 car.
Normally its Ben Collins, he is an ex stock car ASCAR, pick up truck racer type fella, he has appeared without the mask in top gear, once in the EVO rally car racing the skateboarder down a mucky hill (cuz someone left the stig gear back in the office) and also the week where they played football with the 10 Toyota Aygos.
This has been much debated and argued on several circuit racing forums.
