That may or may not be the case. They're probably both bellends. That said, the above is some bollocks that I've seen on FB and also on RX7club. I can't even work out what either of the two morons are going on about. Just reading that one post above gives me a headache.
With regards to Instagram and FB scammers. Yes both platforms are rife with scammers. My advice is, only buy from people you know or who can genuinely be vouched for. There are tell tale signs that most of the scammers have - fairly new accounts with limited profiles, stolen photos which look pixelated when enlarged, listings for items from various different cars. Ask for additional photos maybe with a pic of todays newspaper. And most if not all, want payment by means that have no protection. Let's be honest, no honest/trustworthy seller would offer an item for sale without some form of buyer protection. So if you are unsure, don't know the person or haven't dealt with them before, pay by Paypal goods and services. And as always, if it looks too good to be true, it probably is.
