Hello, I don't know if this was suggested before or not so my mistakes.
I was thinking over night and thought that adding the /swapvehicle command would be great and stop any excessive scams from happening.
How would this work? Well similar to the /transfervehicle command, this one would work almost the same, just that both owners would have to put up their /transfervehicle.
Example: So lets say i'm trading a car for a bike.
P1: Heya I was looking to trade that vehicle for my bike, would you be intrested?
P2: Yeah, sounds like a good offer.
P1: Alright, heres the paperwork for us to sign the agreement on the transfers.
*They both read over and sign the agreement*
P1: /swapvehicle Dubsta FFHH22VS
*Other person sees the notification just like in the /transfervehicle, but he can't accept it before he does his /swapvehicle command*
P2: /swapvehicle Hakucho Drag KJBG351G
*Both players would see a board/notification up top on their screen, one saying that P1 offered to exchange their vehicle as well as his own offer. For this to work both players would have to /swapvehicle accept, for the trade to work. (This could even add more RP scenarios/situations).
I tried to explain it as best as I could, but in short forms similar to the /transfervehicle but both players can swap their desired vehicles, both would have to accept it and there wouldn't be any scams involved.
