The Best Alarm System

[dairel]

I've looked on the internet and did a search on here, and I am unable to pick a security system for my 1994 sl500. I would rather spent more money and get it done right, but which system. The local guy said no way! I've driven to two stores each hour and half away in different directions the last on Sat. and I do not feel good about what they try to sell me, they have never install one in a mercedes or look like kids with a hobby. If I knew which system to use, then I could focus my attention on who installs that make. Any suggestions will be helpful even if what to or what store to stay away from. Thanks Dairel
