Thank you for your input Antti.
The consensus is just as you indicate, that there are effectively no lips on the rear fenders edges. Merely folded-over metal, like you see in sheet metal fabrication to stiffen a bare edge.
The car dealer agreed to repaint the fenders and replace the rear wheel well liners due to the incorrect wheels and lack of disclosure of the car being equipped with non-standard wheels (the car was offered as unmodified, factory original). Dealer also replaced the wheels and tires. In this case, a new set of competition package seven spoke style 601 wheels and Michelin Super Sport tires.
I suppose I could have groused about the car originally coming with the forged 343M wheels, based on the VIN. But I like the style 601 wheels, even if they are cast and slightly heavier.
I'm keeping the car!
