We’ve decided to sell our old Honda Odyssey, and purchase a new one. Have a quote from Carmax already, which is good and one we’d like to accept. In this situation, should we sell to Carmax and then buy the new one? The alternative is to buy the new one, and then sell the old one (which guarantees no lapse in having the vehicle), but I feel it may be easier to transfer old license plates to new car, etc. if we’ve already sold the old car. Thoughts? I’ve never actually sold or traded in a car before.
