Damn kid, you’re on a tight budget but you’re getting an expensive whip? If you don’t put up big miles, consider leasing....owning depreciating assets is not ideal. But if you want to own, I get it, why spend some much on used though?
Negotiating dealerships is a coc waving contest. You can bring the price down by leveraging the saturated market and their need to make numbers....but in the end, they won’t sell unless it’s in their favor. In your case, without knowing what you’re buying and how likely they can sell it, hard to know how much you can knock em down. I usually ask for service incentives over price reductions but that’s just me. Something to think about, however. GL.
