Be very wary of bikes covered in stickers. People will often use stickers to cover up scuffs or other imperfections.
Also, if they've been on a long time and seen a lt of light they will likely leave marks if the paint around them has faded.
I didn't think about that, good point. I thought, I finally found a SV650 with all the bits I Want for a decent price. But the stickers could be hiding scratches etc like you said. I'll skip this one than, the other SV that caught my eye is http://www.ebay.co.uk/itm/Suzuki-SV-650-K8-2008-/191804216328
