Dad sold Chevy's for 40 years so I always got a square deal.
You are not gonna get a new Camaro (or any new car) for cost. Ever.

What you gotta keep I mind is that car dealers and car salespeople need to make a fair profit. Dealers have expenses and salespeople need to eat.
Ask to see the invoice and go from there...(Preferably down in price.

)
It might be a little hard getting much more so early in the annual sales cycle.
Looking at Edmunds.com "True Market Value" is another reference point.
Any chance you have a really nice, clean, and highly sought after trade-in?
If you give the dealer a good chance to flip your trade at a nice profit you can both win.
I invite the active sales people here to chime in.
