Service costs?

[jon-turbo]

Hi all, I've just been quoted £370 for a 60k service on my 2004 Cooper S Works, the guy at the garage said it costs a bit more to service a Works Mini than a normal S?, just want to know if this price sounds about right or should I look else ware?

P.S I was also going to swap the air filter for one of the new ITG Profilter items from LOHEN, anybody tried one on their motor?

Thanks
