The ‘Black Pack’ and ‘Silver Pack’ – for Land Rover Defender. All Defender derivatives will also benefit from a suite of optional features including a new aluminium finish to the vehicle’s side runners, contrast finish leather seats, privacy glass and, for the first time, an ebony Alston headliner which brings a touch of luxury and prestige to this rugged legend. Defender derivatives are now available with the option of privacy glass. The option – standard on the black pack – is available on hard top variants with fixed panel sides and adds darkened glass to second row windows on the Station Wagon, as well as to the alpine light and rear quarter light windows. Due to visibility regulations the rear door retains its standard glass.
