That's crap. When i bought my car from a fellow sau'er in victoria, i deposited $500 bucks into his account straight away (sight unseen), he drove it from victoria to adelaide, i paid for his ticket back, and we set a fixed price before he left (no negotiation)..he came to regency with me, it past inspection then did the cash swap at the bank, then dropped him off in the city... couldn't have been more straight forward and we were both happy.
Guess that's what you get with dodgy people.
