Fortunately, when you purchase a low-powered car from Young Marmalade, the free installation of a black box can cut your insurance premiums into half. By monitoring the driving behaviour such as acceleration, braking, what time of the day the car was driven and at what speed, Young Marmalade provides affordable telematic insurance premiums.
It’s simple. The black box data is used to calculate premiums, if the
car was driven well, the lower the premiums will be and vice-versa.
