What would be the best alarm on the market for a 92-93 500SEL? I am looking at the Clifford Avantguard 4 and the CrimeStopper Informer (LOVE the 2-way pager). How hard should it be to install all the features (including remote start) and integrate the factory alarm (like the flashers on the handles??).

Also, what other alarms would you reccomend? Someone in an old post reccomended VSE (Vehicle Security Electronics), but I cannot find any information on them ANYWHERE. Where can I get some info?? THANKS!!
