G'day I'm about to buy my first bike, and I want to put a deposit on it tomorrow, after which the seller will get the roadworthy and I'll pay the full amount and take delivery. I've checked with insurance, inspected it, and done a vicroads check so all that is clear. My only question is about the deposit. The seller is asking for 10% after which he'll get the roadworthy and I'll take delivery. The guy seems pretty trustworthy, but still I'd like to cover my own arse. I checked the stickies but nothing is mentioned specifically about deposits. How do I make sure that he won't just take the cash and run? Can I put in the contract something along the lines of "buying the bike for the value of $xxxx of which $xxx has already been paid" and get the seller and witness to sign? I'm unsure, as you normally sign the contract when you've paid the bike off in full. Thanks.
