It depends on how picky you are. If you want something perfect, it may be easier getting a different XX.
However if you feel like being handy and wants the challenge of a hunt on parts then keep and rebuild.
You may a little negotiation power with the ins. company. But remember this, the higher value you settle with the company,
then the higher salvage buy back.
Plus you may have a CA branded title, which will surely diminish interest and re-sale value in the future.
It is makes you feel any better-some dufus cager knocked me over on my 97 while I was stopped at red light a few months ago. I thought it was going to be a couple of hundred, estimate was $1,700 and the cager's company paid it. I kept the money and did not replace any panels. It is not perfect, but you really can't tell w/o real close examination. I figure it will help offset lower price when I sell.
