In the UK it was only the climbing, or Cross that was sold I believe. So all petrol 4x4s are the same, just some have lost the badges, trim bits on the outside.
Mine never had the badge "Climbing", only the 4X4 on the left corner of the rear door.
It neither has the glass roof, nor the ELD button (just right of the hazard red knob).
I believe that there are many variations under the same title, depending on the destination country.
From 2005 to about 2009, Panda 4x4s in the UK were all the petrol engined 'Climbing' model, with viscous coupled rear drive. Later models have electronic engagement (automatically) of 4x4, and can optionally have 'ELD' (locking rear diff) too.
Panda Cross in UK were all diesel, all electronic coupled and all have ELD, plus revised lights front and rear.
