This is something Josh Wyatt put up in 2010.
Models, this guide refers to the 2002 and 2003 range;
GLS
This is the entry level model, it is available with the 2.2 and 2.6 petrol engine, and the 2.2 diesel...in both estate and saloon guise. The early GLS's had manual rear windows and black trim, the later GLS's had electric rear windows and wood trim. The GLS has texas cloth trim, either in shale or charcoal. The GLS has electric windows, electric mirrors, climate control, 16'' alloy wheels and the CDR 2005. There are other features, but nothing of particular importance.
CD
In addition to the GLS, the CD has front fog lights and heated front seats and trip computer and rear reading lights. It also has emipre velour trim available in shale, shadow grey or charcoal.
CDX
In addition to the CD, the CDX has Xenon headlights with dynamic beam levelling and headlight washers, electric sunroof, CCR 2006, alram and cruise control, and as standard the interior is velour. The front passenger seat has a fold flat ability to allow the transportation of long items easily. It also has 16'' alloy wheels, but of a different design to the GLS and CD wheels.
I'm suspicious because of the leather seats for starters.....
