Would nice to have one or two customers like that hey Ben!
The other issue is dodgy buyers at the other end - one of my agents does a few cars into Africa, and he was saying that for every 100 emails he sends out, he'd get 20 saying they're interested in buying from him, so to weed them out, he would send them a dummy invoice saying they'd bought the car at auction.
Why? Of the 20 that received a dummy invoice for a car they'd requested that my agent bid on for them, 15 would never contact him again, 4 would say they'd run out of money or apologise and say they couldn't buy the car for a variety of reasons, and 1 out of the original 100 would actually TT the money on the invoice. At that point obviously the agent would go and buy the car, and continue dealing with them, but hell, it's a lot of work.
