guys I have question if I need to buy a wheels from Tesla form parts, how will that's works, how can I protect my self from fraud, any suggestion?
First and foremost deal in person, save shipping. This protects you from fraud but not from being a robbery victim! In most cases meeting someone in a public place / police station is enough to deter criminals from robbing you right then and there.
For those times you can't deal in person, paypal, NOT friends and family! Make sure there is an actual description of the goods involved in the notes of the transaction, including expected weights. If you have this properly documented it makes is slightly less likely someone will ship you a box of gravel. People can still ship you a box of gravel. Dealing with people over the internet comes with risks, make sure the price you are getting makes those risks worth taking. People will always say "if it's too good to be true, then don't buy it" but that isn't easy when buying stuff. I have often paid prices that are "too good to be true" and gotten my products without issues.
I usually start by looking at the seller's profile (when buying from forums) and see how long have they been a member, and how much do they post. The longer and more posts the better. If it has been less than a year I will look at the posts themselves, do they contribute to the discussion? Does it sound like they actually live and breath that issue and, lastly, does it align with the context of that discussion. This takes time, but you are trying to determine if this person is a real person. Real people sometimes have things go wrong unfortunately, and you might still get screwed but hopefully that is a lower probability.
Last but not least, check ebay for the stuff you want. Ebay has robust buyer protections. Ebay is also full of people overcharging for Tesla parts, but you never know. Shop your local and regional Craigslist. You would be amazed at some of the local deals I have found there, and it will likely be much cheaper than on here or ebay. Plus it will be in person, so less fraud risk, and no shipping costs, just your time to go get it.
Good luck!
