I dont think Jazz are sold in large enough numbers in the UK for anyone to stock new after market mirror bodies. Especially passenger side. Even when they are available for a common car you often need to spray it to body colour, or pay them to do it. Jazz ones may be sold in the far east.
Your best bet might be a used mirror from a scrap yard. You may not find anyone has actually removed a jazz mirror and listed it for sale on line. But there will be a number of Jazz in scrapyards throughout the country who will be happy to sell its mirror if you enquire.
There are several 'used part finder' web sites. You enter the part you need and various scrap dealers will e mail you with their price. Its free and no obligation.
Bear in mind you might need to pay the price for a whole mirror because removing one part leaves the rest unsaleable,Also the labour needed to remove the part and postage will be a factor. But as the demand for drivers door mirrors is greater they may sell a passenger door one cheaper.
If anyone breaks just the glass of the mirror you can buy stick on mirror glasses that you glue on top of the broken one. If you cant find a custom fit there are universal sizes that may be a close enough fit.
