Hi mate, I went whit Chriss Knott through the ex-vecs forum last year. They never even asked me if my car had one! For me in my new house in Warrington £800 give or take a few ££'s that's cheap for me ;) try them mate good luck, Also try contacting tracker companies, I met someone recently who got himself an old M5. His insurance told him it must be tracked so off he went looking around. Hey presto it was fitted already. Just paid the £100 odd ££'s and tracked for as long as he owns the car now.
