Re: new car pricing
Not quite, but close.
Dealer invoice $28,800
Minus Used Wholesale $15,100 (Not sure which book the dealer uses - he will be looking at wholesale - what he can sell it at auction today)
Minus Incentives and Rebates
Plus Profit $ ? (What ever you negotiate)
Equals difference price.
I always liked it when people came to me and said, "Let's agree on wholesale for my vehicle, dealer cost for yours, and a profit of $500, or $700, or whatever - will depend on the demand for the vehicle you are looking for, how long it has been on the lot, etc. Then go from there. If everyone knows where they stand, everyone can walk away happy.
Hope that helps. Remember, you want to get the best deal you can, but the dealer and salesperson need to make a profit. So if you can agree on a fair profit, then the rest is easy and it is a win-win. Have fun and enjoy the buying experience, don't let it be a worrisome hassle.
