Just cleaning out back of my forfour found 10p under passenger seat went to pick it up and it disappeared under the air vent, under there, got half of my hand under there and could feel lots of coin's. Checked driver's side and the same , .will need to take carpet up to get out ,or vacuum cleaner,but as I need a new clutch all monies welcome. Could do a contest to see who can find the most as it looks likes the floor slopes down that way ,and is a little money pit. Ps winner get to send me half the money they find, towards my new clutch.
