Glos Guy The 2021 X1 X-Line has full leather heated seats as standard (front) with minor electric adjustment for seat bolsters and lumbar support if chosen as an extra cost option. The Sport model has cloth trim but is equipped with sport seats as standard.
Front and rear park assist, power folding mirrors, Auto dimming rear view mirror, front and rear exterior LED lighting and wireless phone charging are all standard on X-Line. Previously X-Line only had front LED lights and rear parking. However, sliding rear seat is now a cost option.
18″ diamond cut alloys with NRF tyres are standard on X-Line but painted black on Sport Models along with some lovely black cladding along the bottom of the doors which I know you like:) 19″ alloys are an option on X-Line which are a nice addition.
Privacy Glass is an option on X-Line and Sport models and sport seats an option on X-Line.

The optional extras I chose were sport seats, privacy glass, lumbar support, auto dimming rear view mirror and power fold mirors. All except sport seats and privacy glass are now standard no cost fit options.
