You can do it and I am certainly going to do it next year (dates TBC)
It happened a few weeks ago with a whole range of cars and only a couple of BMW's. I predict 2007 will be in demand as it's just not well known and the first time it;s been run in since 2002
3 day event £70 per day - you don't have to enter all 3 of them
>Hill Climb in Douglas city
>Pursuit event
>Hill climb on the TT course outside Ramsey
Cars this year included E36 M3GT:

Harge 325

Ford Gt

Plus, all kinds of classic performance cars, UK and the USA, plus Porches, Corvettes, a 8lts Moggie minor...all sorts..oh and a model T ford!
Who's up for it? Legal driving, on closed 'A' roads at 125mph+, come on, you will never get to do this anywhere else than the Isle of Man - once in a lifetime me thinks
