Re: Where to buy GruppeM or other CAI..?
Brisk LGS are available from MBM/KBS and Juzz4Cars. Both sponsors here.
Alternatively, you can buy online for cheaper if you are into DIY. How cheap depends on how much research you put in. There used to be a guy based in Canada who sold them at literally cost plus. It was about a quarter the cost of local pricing. But I think they have been closed down after all the agents worldwide complained. FYI, plugs in Singapore cost easily at least 2X more than elsewhere.
