I have to disagree strongly with Philbar here. The total cost for 2 people for the weekend is just over £200, that is camping from Thursday until Monday and entry to the circuit on Thursday (to set up), Friday, Saturday and Sunday. If you attend an event in Europe surely just to get across the water with your car will cost over £100?
Music is obviously very subjective, personally I loved Bonnie Tyler, Status Quo (1 hour set), The Boomtown Rats and The Stranglers. Having said that from a value for money point of view tickets to see Status Quo outside Silverstone were well over £100 for 2 people. The Bootleg Beatles who are playing this year sell out tours all over the world. They are playing the Royal Albert Hall in June and the cheapest tickets left (only 11 left) are £87 per person. So again value for money wise Silverstone is pretty good.
As to the static displays I have only ever seen 2 Ferrari Enzos and they were parked beside each other at Silverstone last year. There are always loads of Lambos as well so not all Porsches or BMWs. Last year I went drifting in an F Type jag and did the off road course in a Range Rover (obviously as a passenger lol). I even got to shake Mike Brewers hand (he approached me I was not stalking him). There is a lot to do without even looking at car racing and it is all included in the entry ticket price.
However the car racing is fantastic and even though the cars are worth millions it is proper racing with bumps and scrapes. The all access pit experience is absolutely great as well. My highlight from 2016 though was Mika Hakkinens old Mclaren F1 car screaming down the Wellington straight, it was spectacular.
Obviously I respect Philbars opinion but I had to put a balanced side to the discussion and if you have not been before you will love it, this will only be my fourth year but I still look forward to it every year
