I would tend to agree.A car maintained with authentic parts would be considered low miles with that history. Yours has been modified. Nobody knows.
What's more concerning to me are cosmetic mods. I have no supporting data besides a hunch and healthy bit of cognitive bias, but I feel that MANY cars that are cosmetically modified are done so by owners that very poorly maintain their vehicle's mechanical.
There are exceptions to this rule cough @Verdugo
