So much this ^
You really need to ask for a few pictures of the item on all sides. I got some gtr gauges off a well established member who said they were in 'great' condition. I received them with black glue type shit all over them, spray paint, and broken tabs, all because i never asked for more than the 1 blurry picture.
If someone is evasive and won't meet up to sell the goods, the chances are they're not in the condition they were described. Or possibly stolen and or not even in possession of the seller.
I think a few people remember this time last year, a seller on here was selling a clutch and ecu and a few other expensive parts. The parts were not sent and seller was un contactable. The same thing happened to that guy who bought a power fc from ben ellis.
If the seller wants a sale, he/she will open a paypal account or meet up or send photos, it is not hard and takes a total of 1 minute. I've had a few guys open an account for me.
Maybe we need the trader ratings under our club affiliation with a % of good or bad trades, a lot of forums have these now days.
