MX5 Donor - What mileage and price?

[Blacktop]

I am starting to look for a donor vehicle (1.8 mx5 130bhp) and seen a couple for sale but just wondering what are peoples opinions on the maximum mileage and price to pay for one with a bit of mot and tax left on it (so I can get it home)?

I have seen one locally for £875 with 118K on it in Black with rear spoiler and leather (but drivers seat is ripped). Is this good for the money or a bit less after haggling???

Obvioulsy unwanted parts will be sold so does anyone know what MX5 parts are desirable for selling on?
