Unfortunately, Sherlocks main mechanic has finished for the winter. I've used them for the odd job when specialist tools are required and they do a good job at a fair price. I was in there last week and they told me that main guy has finished but they have another chap working part time I think. I need them to refit the rear drive shaft for me as I don't own a hydraulic press (but it is on my Christmas presents list)Worth phoning them to check they they can do what you want. Never just turn up unannounced as they might not let you in.
Alternatively, I have a fully equipped workshop if you just need simple tasks doing such as fluids and filter changes etc. Just so long as its not a full canbus fluid change, I can't run to that.
