2003 Mini Cooper S. There is a "stumble" when starting off in first gear. The car seems to lose power and lurch momentarily. No combination of clutch and gas pedal motion seems to fix this. Issue has been heavily documented and discussed on Mini enthusiast forums, so it is not a driver clutch-user error.
