As already said, leave out the mileage - they'll ask. They may hang up, but they called...
I'm not familiar with the Voyager, is there a variation, such as LX, GL, etc? If so list it, and any options such as power windows, PDL, sunroof, etc. Rear air? Two tone?
Be prepared to field the calls, too. I've called on ads & gotten lousy answers which turn off buyers. Especially, young children shouldn't answer while an ad is running if at all possible!!
Answer any questions honestly, but in an upbeat manner. When the inevitable question "What's your low figure" is asked, be politely evasive. Whatever you say, they'll underbid it later anyway, so why show your hand too early?
When a caller is coming to look, have the vehicle as clean as possible. Buff & wax it NOW so that'll be done, a shine does make a difference. Even shiny
dents look better!

A $2 can of auto deodorizer is well worth it.
Have any spare parts accumulated? Box 'em up & give to the buyer. They love it, and it clears the junk out!
Have a bottom figure in mind &
stick to it, even if lower cash is waved at you. Also, be prepared to turn away over-critical shoppers that act like they might come back with problems, which brings me to the next point...
CYA - make out an "as-is, where-is" statement that meets your state's laws. BUYER must sign it! Here in MO, any vehicle MUST pass emmision inspection & it's the
seller's responsibility to pay for it, up to $800
regardles of selling price, except for "sold for salvage" vehicles. Can you guess what a buyer has to sign if
I sell one?

For any price!!
An unwitting seller could actually "sell" one & LOSE money, be better off junking it! I tell anyone point-blank that once it passes my curb, it's YOURS. It breaks going home, you own it. Period. I've likely turned off a couple folks that way, but most appreciate honesty & I've never had one haunt me yet. I know people that HAVE, though..

Years ago, at the last minute a buyers father told him to refuse the "as-is" statement. Told his son "you sign that you have no recourse"
This was on a $700 truck! I handed him back the cash & refused to sign the title. It was that close to done! HE left pi$$ed, but that was the end. Better than risking getting sued!
Lastly, sales tax laws differ by state. Here, a vehicle sold within 60 days either way of the date of purchasing another qualifies for a partial refund of the tax paid on the new one. For example, you buy a new-used one for $5K and pay 7% sales tax = $350
Then, you sell yours for $1500 and apply for the refund. You should get $105.
Check with local license office BEFORE you sell, they may have a form which requires the buyer's sig. You have to ASK for that info though, they seldom offer it!
