When I sold my SV650SK03 in May, I had lots of extra's including Remus Titanium end can, R&G bungs, Ermax undertray, Ohlin's suspension, new Metz Sportec M1 tyres, braided HEL lines and Datatool 3 alarm and still only got £4000 from a private buyer. That's was with 6000 miles and FSH. If someone offers £3500 you are getting a good price. Trade in price depends on what you buying/discounting. Suzuki dealer offered my GSXR600K4 for £5995 but would only give me £2700 for SV. I ended up getting my mates GSXR600K02 for the same money (£4000) as I sold the SV for. Bargain! However, I just found out I have a £2400 bill waiting for me when I pick up the bike tomorrow as I had a couple of 'extras' added

Maybe bargain isn't the word!
