I've just got a second hand SL350 (2005) - I have been having a few false alarms - these normally seem to happen when I park the car and raise the roof.
I've tested this myself and can never get it to happen outside my house - it always happens when the car is elsewhere.
AIB understand your special Mercedes deserves a special insurance policy. We have a refreshing attitude to insuring high performance, modified, imported or classic and vintage cars and deal with the UK’s leading insurers. We offer discounts for length of ownership, where the vehicle is kept overnight and limiting the mileage and can also cater for those clients who need higher mileage and business use.
