To those who are concerned about vehicle purchasing:
On the current version of our "Car Dealer NPC" we have never faced any of these issues. Unfortunately as the buttons are very close together, it is very easy indeed to select the wrong option (I personally did so when the map first changed.)
Either way, there's unfortunately no way we can fairly refund you unless you have a video showing the time you purchased it. If you do have this, post it in the help section with a more coherently written topic.
Regards,
