I've only scrapped one but I took a few cosmetic bits off first...rear lights and panel, spoiler, front strut brace, that kind of thing.
I then phoned a couple of scrappers and went with the best price. When they rolled up naturally they offered me a comedy price, so I said 'OK, see ya' and walked back in the house, and immediately they 'had a word with the boss' and the price came back up
You're right that you'll only get about £100 from a scrapper though. I couldn't be bothered with the hassle of stripping it personally as my time is limited, and as you say, it can make it more difficult to get rid of whatever is leftover. I don't think there is exactly huge demand for F parts either these days, so you might end up with a lot of unsold bits cluttering up the man cave
