In all the time I owned Dave'sF1, the only problems I ever had was a suspension light one time that led to me learning more about shock actuators than anyone should know and the normal alarm siren problem.
I even got to the point where I figured out how to modify a Corvette actuator to work in a Ferrari. Coincidentally the car now has a Corvette siren as well.
Strange bedfellows, no?
The car has never failed to start, run perfectly, and has never let me down in any way. This includes probably a dozen or so track events.
