I had an R1 and my only Cossie experiences are my mates Saph's and 2 Escort Cossies(all stage 3)...... tough one really but I think if it was me then I would have a bike. However you probably get a lot more use out of 3 door......... If it was an Escort I would have that EVERY time. Other thing is the bike will lose money like mad, bikes are replaced so quick now, the 3 door should hold price and maybe go up.....

Sorry can't really help much but that's my opinions. Bikes are bloody great and learning to wheely is one of the best things I can ever remember(some say it's showboating but once I had learned I couldn't care who could see me and would do it in the middle of no where as the feeling is second to none!!! )
