He he, no, ride what you like man.
I forgot you had yours imported, and lifted my eyebrows when seeing your asking price, at more than what I paid brand new and was puzzled. That's where I was coming from.
But really you can't expect your extra costs incurred with personally importing back, or base your asking price on it.
Thing is you can get a brand new UK one for £435, in orange, and medium if you just wait a little. The UK 'Mythic' frame comes with a Banshee head tube badge fitted in place, and Banshee decal tube stickers lose in the box, so you can fit those if you want Banshee on the frame tubes.
You should sell the frame easily and you may well get lucky with the price as the Paradox is currently a hot frame, and I wish you all the luck with it.
You just need to find an impatient Paradox gang wanabee 😉
