Yeah, either get a pre '03 Banshee, or a pre '03 Banshee frame with a title and swap all your parts.
I had bought an '03 Blaster which I knew had a red sticker. I thought I wouldn't want to ride in the summer anyways. Boy was I wrong. So I sold that one for $2k and got a '02 for $1650 that just had a fresh top end put in it. So I made some money on the deal and got a green stickered quad.
Yes, California sucks like that.
