I'm thinking the Armster might not fit the later cars as Fiat swapped the handbrake from the flappy thing to a normal lever.
I guess they would have also change the centre consul to accommodate it.
Hard to tell, but does it look like a 500 Armster will fit?
The cup holder at the bottom of the pic doesn't quite look like the one in my Abarth.
Also @Goudrons is the gear shift in 500 a bit high as it is in panda?
Yes, it's in the same place and feels about the same height.
