Hi there just fought I'd share my experience, I took my 225 to a garage a chap off Clio sport recommended called 519 Automotive, just off the A1 black cat in Colesden. Danny gave me all the advice I asked for and checked the car over for me too as I'd only picked it up on Wednesday!
He really knows his stuff and has a great little setup there. He will be offering tuning too at some stage! Booked my cambelt and service in already!
