I thought I'd chuck my 2 cents in as to me, it's an interesting topic, with passionate opposing sides.
When I bought my Pinz it had this fancy camo paint job but under the law here it has to be removed "something about a load of ex army trucks emptying a armoury out".
I also lean towards the, trying not to alter a car too much, so perhaps in years to come it could be converted back to originality.
If a car is being shown at a historic show it should be original (ish)
But I think an owners vehicle is his and they can do what they want because:
- it's his/her money
- a least it's a vehicle saved, to some extent instead of being scrapped (gone forever). I hear there is a bright pink armoured vehicle driving around in the UK. Once that owners group gets weary of it I am sure it will be rebuilt or parted out.
