I have the concept 300 with remote fog lights and remote engine start, brilliant alarm, occasionally have problems with the locking mechanisms becoming de synchronised i.e. does not lock when alarm is set, no big deal though.
good luck make sure you get an approved installer to fit it to ensure a good job and also to ensure insurance approval.
Where you based? If you not too far away from J23 of M25 then Rtec have one of the top 3 installers in the country and he is brilliant.
