The dodge is actually really growing on me, to the extent I prefer it to all the others. However I still dont think it could be the OGB's main car. It looks bloody awesome but it doesn't have the scale or grandure to be a main OGB car. To be honest I think all (except the future car) have merit.
I can see the Hummers being used by teams in more wild states and countrys, like Nevada, or Canada. The Dodge I see being used in London beautifully.
This is the GBUK vehicle, please take a look and see what you think
