Shop, shop, shop.
Treat it like you’re bidding it out. Email as many dealers as you can. Be polite; tell them what you’re in the market for and don’t hide the fact that you’re shopping around. Make it known that you will buy from whoever gives you the best bottom line price.
When comparing prices, be sure you’re comparing apples to apples. One dealer may have a doc fee, another may not, but the one with the doc fee’s overall bottom line could possibly be lower. Same with delivery fees. Look at the bottom line.
And, as somebody else said, you should be able to find the invoice price and, from that, extrapolate dealer cost.
After emailing several dealers, you’ll start to get an idea of what they’re going for.
You’ll probably discover that there are a few volume leader dealers around who make their money by selling a lot of vehicles instead of making a lot on each individual vehicle. So don’t be afraid to buy from out of town. Just be sure your demands are clear and that you will not sign for it if it’s not exactly what was agreed upon.
Good luck!
