Value of a stick dial GMT II Pepsi

[LaurasOtherHalf]

I've long fancied a Pepsi and today a mate said he'd been offered a late (2008) GMT II Pepsi for quite a good price, i.e. what you would generally pay second hand for a nice standard GMT.

As it's such a late model, there may be a chance it's a 3186 stick dial although I haven't seen it yet.

I've seen people ask crazy money (IMHO) for them but what is a realistic value of one in the UK? It would be nice to have the new movement in the old "last of the original" style watch.

I may add, I might have first refusal if said mate doesn't buy it. Thoughts?

Still awaiting confirmation on serial number although to be honest from my research you really can't tell until you pop the back off and check the movement.
