Many top of the range cars come fitted with a host of extras – but not many include an arsenal of weapons including a machine gun.
And this 1924 Rolls Royce Silver Ghost also comes with features such as a picnic hamper, a full silver set and champagne flutes.
The car will be taking part in a rally with nine other Rollers worth millions of pounds at Hampton Court Palace in Surrey tomorrow.
Owner Andrew Courtney, who has had the guns deactivated, said the rich used to take the weapons to protect themselves while touring.
Mr Courtney’s Thompson submachine gun and Webley revolver are neatly concealed beneath the running board of his vintage model.
The retired engineer, who helped design Margaret Thatcher’s nuclear bunker at Whitehall, bought the Silver Ghost in 2000 for £100,000.
It was originally owned by a woman from Maidenhead before travelling to Australia and later back to Britain. It is now worth £300,000.
Mr Courtney, 60, joked that the weapons ‘would have come in any handy in any verbal dust-up with overzealous traffic wardens’.
His metallic grey motor carries five passengers in comfort but it is an expensive hobby because the 70mph car manages only 6 to 8mpg.
