Thatcham Category 1 Alarm/Immobiliser

[bigdr]

my insurance company requires the fitment of a cat 1 alarm/immobiliser to my 1971 280 SL pagoda. I have two questions - 1) can anyone recommend a suitable security system for a classic convertible. I want the system to be as unobtrusive as possible and 2) Recommend an installer that has experience of classic cars in the Herts / Essex region (although I ma prepared to travel if needs be).

Many thanks in advance.
