Hi all. I'm wondering if the community here could help me price a damaged macbook air. I have a good friend that would like to buy it from me, and since he's a good friend I'm not so interested in getting the best deal I possibly can, but just a fair price; his motivations are the same. Machines with a similar spec go for around £500-£600 on ebay.co.uk (I won't list all the specs here, but it was new around 15 months ago.) Unfortunately, it was damaged in a bike crash. The track pad is smashed, and the case is bent. Photos are attached. Everything works fine, however, although the click button is a little temperamental: it works, but only on some parts of the area it should, and only on solid surfaces (e.g. tables, but not laps). I'm not sure what price to go for, so I thought I'd solicit opinion here. One way to price it would be to get a quote for repair and deduct that from the £500-£600 price on ebay, so another question is what sort of ballpark figure that might be. (I won't actually get the repairs done myself; it's up to my friend whether he wants to do that, or just use the machine as it is.) I should also mention that I'm prepared to offer my friend a 100% refund if it dies within 6 months, and 50% if within 12 months. Thanks in advance for your comments.
