1981 Mercedes-Benz 500 SLC Coupé estimated at £25,000.

If barn finds are the holy grail for car collectors then this selection of 12 vintage motors worth £2million found languishing in a Swiss schloss is something else.

The stunning collection, which boasts an iconic 1921 Rolls-Royce Silver Ghost, was started by a wealthy car enthusiast in the 1950s but since his death has remained largely untouched.

However, the original owner's son recently rediscovered his father's haul and will now offer it at auction.
