Well the dealer told me that it was A1 and had had no paintwork done - but I have found overspray on the rubbers between the wing and the back wheelarch (and on a leaf trapped in there - quality job it was not!). Plus there were two missing screws holding the wing on. So something is amiss.
The log book says nothing. But it was made in 2012 and registered in 2014 and two years is a long time....
I'll have another look at the front chassis rails as these looked galvanised and I do have the photo build which I thought showed a galvanised chassis - I'll have a look. It could well have been undersealed but why would the cross rails have been painted (they have chrome covers)?
I'm gonna have a good investigate later
