Hey this dent appears out of nowhere on my wifes Mini (a BMW brand) boot / trunk with a slight surface scratch overall about the size of a credit card.
First of all you go through despair & anger, then we called "Dentbusters" out of the yellow pages this guy takes thirty five minutes and hey presto even close up you cannot tell where the dent was. If your in the South East of England go onto www.dentbusters.co.uk they cannot come more highly recommended for dent removal.
