Were WS Zetecs 'fully specced' from launch?

[LeadFoot81]

Hi all, I'm in the process of hunting down a WS Zetec for myself (preferably a 3-door) and I was wondering if there are any differences in standard equipment for either shape (3 or 5 door) or if standard equipment changed for the Zetec as time went on.

I ask because I had a look at an '09 3-door that had aftermarket Bluetooth fitted- does this mean that none of the '09 models had it at all, or was it an optional extra that some '09 examples may have fitted? (which became standard at some point?)

My budget will probably restrict me to an '09 Zetec, I didn't get a chance to play with the aftermarket Bluetooth but does anyone know how well these units integrate with the car?
