Add new question to the seller

This surely sounds like a scam but if it isn’t please advise if it’s still for sale, beware I will recognize any and all suspicious type responses / requests from a seller and will not fall prey to anyone trying to pull off a scam, anyone reading this should not deal with this seller if there isn’t a reasonable response to this message,
Rule #1- never try to purchase anything online that’s seems too good to be true
Rule #2- never deal with anyone from outside your country that has posted an ad specifically outside of their country, why would anyone want the hassle involved with that, think about it
Rule #3- never deal with anyone that has weird answers to any of your questions, such as- your friend cannot inspect for you because it’s in a sealed shipping container for fast shipment to you. I end up with the item in a divorce settlement, etc. These two are responses are likely the most common but there are many lame answers from scammers.
Rule #4- Think twice about any older than a couple of days that seems too good to be true, there are literally millions of people buying online every minute of the day so if too good to be true item hasn’t sold fast there is a legit reason as to why, SCAMMERS are everywhere and this seems like one, the Gibbs Quadski’s sell new for at least $40k USD so if one is for sale at $6k it must be wrecked and not useable otherwise asking price would be substantially higher, anybody on the planet that owns or has used an ATV and PWC would buy one of the#e for $6k all day long if it was in decent working condition.
