In that case you need to let your fellow evo friend do his job on yours.

I think what people fail to see is that yes, hand assembled and finished cars all come with their share of “human error”, regardless of price tag. Proper, gentle care is what keeps them sharp - but if the car actually got this bad, the previous owner simply wasn’t bothered by dirt and swirls. Even in the upper echelon of cars’ owners, they can really still be “just a car”. Believe me with the mockery of this trade in this area, it really just confirms that real preservative work is for “car people” only.
