^^ That is BS since you did not pay current pricing. The simple and honest line is that you are tying to wring out max profit from a flip. I might be doing the same shortly since the car I ordered in October is not actually the one I expect to keep long term. So I'm not going to judge but I do appreciate honesty.
Since you are trying not to offer a price discount, this comes down a trade-off: earlier delivery without being able to choose options, not getting a new car, having to deal with you as an unknown quantity, and perhaps delivery risks. Someone who wants exactly what you picked, is pressured to get a car now, and is local to you may look favorably at your offer but my guess is you are going to have to be lucky.
I don't know how typical I am, but as I buy more expensive cars I have gotten more picky, and a lot less tolerant of risks related to buying a used car. I'd also guess that you are are playing in a market where people can wait a few months for delivery. I'm not trying to persuade you of anything, I just was interested enough in this game to think about it a bit and write down my thoughts.
