A few times but a lot of people on have too. We also hosted the GTIROC track day event there 2 years ago IIRC we had about 10 R's went on track.take it you've been oulton park before campbell , been from manchester there's a few tracks up north but all the best seem down south
In the North you have Outlon, Cadwell and Anglesey all close to Manchester so I would say we've got it pretty good.
If you and your mates are a bit worried about it all, Elvington is a good safe place to cut your teeth without fear of a crash or race cars out testing. Cheap too but watch out for tyre wear on the abrasive tarmac.

Oulton also do Novice only days which would be the best place to start for you and your mates if you're all new to it.
