I'm not sure what your tax rate is exactly but a good estimate is about 5%. If that's the tax rate in your area you'll have $1,099.40 in taxes. Add another fifty or so for license plates/transfer. $35 for the title transfer fee (assuming you're buying from a dealer and are paying bogus fees.) Watch out for more bogus fees like "document preparation fee" often called doc fee or "dealer fee." Just consider those as part of the price of the car. What looks like a great deal when you just consider the price of the car can turn into a real clunker of a deal once the dealer adds all their bogus fees.
If you're over $23,250 out the door something funny is going on.
By the by, you ought to be able to get a killer loan right now. If you've got decent credit (anything over 700 beacon) you should be able to find close to 5% - 6%. If you've got just OK credit (640 - 700 beacon) you should still be under 10%. If it's over 10% you've either got terrible credit and shouldn't be buying such an expensive car or they're taking advantage of you. Always shop car loans when you're buying a car, don't just take the dealer's offer or your credit union's offer without shopping other places.
