<prompt> Human: Hi guys, I just got this letter from a nearby Nissan dealership that looks interesting.I need a 2011 Nissan Versa for our lot. Im willing to authorize the purchase of their trade-in by giving them 3 years of additional trade-in value, based on current market value. I have a potential buyer for this vehicle.Have any of you heard of something like this before? Is this a sort of sales tactic to get me to buy a new car off their lot, or is this a really sweet deal and I shouldnt pass up the opportunity? How much extra value is 3 years of depreciation?Im in the market for a new car, but mostly because I need a second car, not to replace my 2011. Im not really that interested in Nissans either, are they able to authorize this trade-in and then get me a car of a different make? I have no idea how trade-ins, or really any of this works.Thanks!Assistant: Its always amusing to see how they try to make these mass mailings appear personalized. Obviously they address you by name and use data they know about your car. Oftentimes they use a font that looks like real handwriting. Most recently, Ive started to see them even print fake ink smudges on the page to make it look like someone really did sign it by hand.Human: This one actually had a sticky note on it with his personal info, with a hand addressed envelope.  <response>: Yes, and so did the letters sent out to hundreds of other customers. You have a Nissan Versa. Its not a rare car. There are dozens of them on used car lots in your area. Theres not a prospective buyer lined up for your car. Its all bullshit to get you into the dealership.
