I know what you mean Nat. I e-mailed a guy yesterday asking for better pictures of his "practically showroom condition" Kawasaki (he'd used mobile phone type pics in his ad.) and his return e-mail said "those are all I have".
Now, if I could see his bike in detail (and it matched his 'brief' description) I'd probably buy it - despite having nowhere to put it! But if a seller won't make any effort, then why should a buyer? Makes me mad.
Contrast this with the web-site ad. I'd placed when selling my Strada. Took me bl**dy ages to do!
(..oh well, anyone living in Rugby want to view a bike for me..?? And send me some 'good' pictures? Pretty please..!!)
