+100000 what Lexx said about Falcon Performance. Lee and Dane knows the Zed like the back of their hands. And if you need any almost new pre-owned parts rather than brand new OEM parts, they could source them in a matter of hours. Personally i won't let Evans Halshaw touch my Zed..not sure about the one in Boro but the one in Mansfield, Nottingham is rubbish. Avoid Evan Halshaw like a plague!
I don't have my Zed anymore but i will still be going to Falcon for my beamer's future needs..AND i don't even live in the Northeast. That says a lot. You can't go wrong with a performance garage that serviced high end supercars and they are part of the "Good Garage Scheme".
