When I got my 420SEL a couple of years ago -- in mint condition overall, I found that the alarm system was touchy and would go off in a high wind in the parking lot!! I just went under the right floorboard and disconnected both alarm cables, which stopped the problem. I think alarms are often more problems than they are worth anyway. Ben Carter
