Ryan has a lovely Norfolk Mustard (yellow) M100 in Topanga (Los Angeles), CA for sale. I can vouch for it being upkept to high standards. Can't find the info at the moment on it, but I would guess mileage around 70K and price around 15K or a bit more. PM me if you want his contact info.
His is the yellow without the chrome wheels in these pics
here's me and him on a topanga canyon drive:
