They are certainly trading but not advertising much as, in the words of Andy Attwood, they are busy doing a lot of restoration work at the moment. They certainly do appear to have plenty of work on at the moment but of course they are not exclusively Maserati.
Despite being an ex-Maserati tech, Andy didn't seem to know of the GS LE spec which I was somewhat surprised by.
I was quoted £700 + vat for labour and £750 + vat for a clutch for a GS (off the top of my head, notes are at home). By comparison, Voicey advised that if replacing the clutch doing the release bearing and flywheel at the same time.
I have seen a McGrath PPI report and it looks brutal by comparison to what SCC produce.
I cannot comment beyond that.
