If you added up the cost of everything (including clothes, registrar, venues, food & booze etc.) then me and my wife spent around £75 per head on our wedding (so close to £8000). Unfortunately they just cost quite a bit if you have big families or a lot of friends you want to invite.
You're not BU to be shocked at the cost (that £75 is way more than we thought we would spend when we started planning). Just make sure you shop around and always make sure you have a go at haggling the price down.

£2000 at 1987 prices would, I believe, be around £4,900 - £5,100 today. But that's assuming that all costs have risen at RPI, which they haven't (i.e. they've increased more than that).
I don't think most 'modern couples' do spend £30,000 (or whatever amount the Mail or Telegraph like to quote and get outraged about). The amount couples spend today might be more than people did in those rose-tinted halcyon days of yore, but that's because weddings are just expensive nowadays (for instance just a church service would cost you £500).
Even if it is in a church hall or similar venue (as ours was) it can still be incredibly pricey (corkage charges, the cost of getting even a very basic caterer in, linen hire, crockery and glassware hire...it all adds up).
