My DD is a base '99 with 152,000mi on it so far. I put about 3,500-4,000 miles a month on it and it has never stranded me or broken down. Plenty comfortable.
Oh it needs a fair amount of regular service and maintenance but has never actually broken down.
I think the mileage on the one you're looking at is pretty typical and a good starting point. Not too much no too little.
Price should be negotiated down some.
