The Honda is the best of the three vehicles. You should check with Kelley Blue Book (kbb.com) to see if the $14,000 is a fair price for that vehicle. If the price is higher than the "private sale" or "retail" value at Kelley, you should negotiate a better price. If it's less, there's no need to negotiate at all, unless you feel you might get a few more dollars off the price by doing so.
