Reminds me of a time when I owned a Chevy 4x4. The 1st foul out of the block was a bulge in the sidewall of one of the tires.
I took it back and told them to fix it. The guy I bought it through claimed his wife (in ill health) had to take the truck somewhere else to get it fixed. Really?
The analogy is similar on many levels. Sure, yer pit will hide all that in time. That's NOT the point. I couldn't see the brakes, transmission, vacuum hoses, steering, suspension, (I could go on).
Make the seller aware of the issue and wait for a response. If they don't fix it to your satisfaction, kick it up a notch.
Yours is the 1st thing I've ever read of that would imply the manufacturers integrity. The pics are quite clear however.
I don't know that I'd be filing a claim for a new pit; but a discounted price for a scratch/dent model should surely be in the offering regardless of the damage location.
