Clean Sapphire cars are hard t come by, at least they were when I was looking. I have been loosely following the market since I bought mine and have not seen many I would want. That said they are the best color Vipers come in. I may be a little biased though. Good luck with his search.
I have a very clean sapphire/silver with tasteful mods that I would let go, only problem is it has 35,000 miles. I put on about 7,000 per year. Car has only seen rain twice in the 3 years I have owned it.
