BMW 116i SE - Vibrations through depressed clutch pedal - cxgcxg

Hello, I went to test drive a 2005 BMW 1 Series yesterday and noticed at low speeds when shifting down (i.e. to 2nd gear to take a corner) I could feel some vibration in my foot through the clutch pedal when it was fully depressed. No obvious isues changing or engaging any gears. Not sure if I should be concerned...I put a deposit on the car!!
