Bl00dy h3ll you're a hard crowd to please!!
Each to their own and all that?
All the mods would easily be reversed, indeed the owner may have all the bits to return it to stock.
I don't like it either, but I applause the fact that the owner at least engaged with his motor car and he's not hiding anything in the sales literature.
My initial concern viewing just the advert would be the price / mileage, not the mods.
