I didnt want to sell my VR4, I loved it. But it was getting old, lot of miles and I wanted something newer and nicer. I also had someone who made me a good offer for it so I was able to pay off my bike, my credit cards and put money down for my S4.
I have no intentions of ever selling the S4, but then again I didn't either for the VR4. Everything is for sale for the right price i guess.
