How often does the clutch need to be replaced on 2000 Nissan Altima

I am supposed to look at a 2000 Nissan Altima in an hour. He is asking $5200 OBO, 69,000 miles. Do you know at how many miles the clutch needs to be replace and how much it costs?

Asked by for the 2000 Nissan Altima
How long a clutch lasts is extremely dependant on the ability/skill/experience of the driver. I've replaced clutches at as low as 19K and as much as 230K(original-highway miles).
Ok thanks for the reply.
