Loch Lomond is one of very few clubs in the UK which actually is private - Members and Guests only. I can think of the likes of Queenwood and Old Head which are also like this.
I believe a debenture at Loch Lomond was circa £50,000, almost unheard of for a UK club, although Queenwood is even more expensive.
The Members paid their money to have a course that is basically empty for use as they please. As has been mentioned, it does have quite a corporate feel to it.
Unless the new owners come in and basically keep things the same (highly unlikely), then the current Members will lose out either financially or in terms of exclusivity, access etc. Whether this is actually a good thing in the grand scheme of things is open to debate, that it will be to the detriment of current Members is pretty obvious in my opinion.
