Doubt they paid over 40k for the trade and also highly doubt they're going to get 46k for a black SS 5k miles or not, manual transmission or not.
They could have took your 2K and made a profit in a week instead they're being greedy which might pay off for them but most likely not in my opinion unless the perfect buyer comes along. Yeah, we'll see what happens.
