basically going to be upgrading to a Honda CBR600RR soon. had a run of bad luck with my current bike, so my dad suggests i go with a dealer when buying the next one so i get a warranty and the assurance that its been looked over by mechanics, the bike at the dealer (Peter Stevens) is an 2006 Honda CBR600RR for $10,500 on road. or would i be better off waiting and snapping up an 07 or 08 Honda CBR600RR for around the same price from private sale? can there be many problems with a bike thats only a few years old? cheers.
