I know I'm opening myself up for some

not to mention

as well as

but as I am outside the US I think I can get away with asking this without incurring the wrath of all you people who have been razzing noobs for asking old questions.
I am in the UK (hey, it's not raining!) and I want some subtle body styling mods for my e36 but don't want to pay ££££££££££ for it.
Can anyone recommend any good companies that they have used/heard of?
Your help is appreciated
