I'm considering buying an almost new 'Boxed' Canon 5D mk2 and 24-105mm F4 L lens in a private transaction which is advertised as being bought from one of the largest National photography retailers in only May of this year. The seller claims it's all perfect and he has the receipt and 10 months remaining warranty. He will sell it to me face to face and I can collect from his house. However it's so cheap and the circumstances so odd (he needs fast cash but wants to buy the same camera again as soon as he can afford it) that I'm a bit suspicious! He wants a third less than the price he paid for it just two months ago. Claims he's taken about 300 pictures, max.
What sort of things should I need to look at? Presumably obvious wear and tear indicative of its true age, but a 2 month old camera should look pretty mint. What about the documents, receipt, etc? Any serial numbers I should check or anything? Maybe it's just a good deal, but the seller seems very young, and... maybe I'm just being prejudiced..?
what do you all think??
