LEATHER upholstery is standard on the convertible, replacing the cloth (City) and velour (CD) trim of the mainstream Astra models. The door inserts are also trimmed in leather and have a gathered or ruffled finish that reflects the "loose" fit of the seat trim. Black leather is standard across the five exterior colour choices - Star Silver, Breeze Blue, Europe Blue, Chianti Red and Carbon Black - although Star Silver and Carbon Black cars can be fitted with red leather upholstery as an option. Driver and front passenger seats are both adjustable for height, while the driver's seat also has lumbar adjustment via a dial on the inside edge of the backrest. Heated front seats are standard on the convertible and feature five temperature levels.
