My 99 740 is a great car to drive. Needs a little mor power, and maintenance is costly, but damn fun to drive.
My alarm goes off intermittently. I park the car and lock it. sometimes just after the 60 second timer finsihes the alarm starts, sometime it starts after 3 - 4 hours! Soemtimes the car can sit for days without any alarm malfunction. The interior motion sensor works, the alarm seems to work fine except for the totally annoying blast when least wanted.
