"How often does it need to be changed?
The oil, every 40,000 miles, the filter may need to be changed as well."
At 59k with no previous record of a change I would give it a miss. I know its annoying when you think you've found the one, good mileage, right price, right spec etc but you'll be kicking yourself if you get hit with a massive bill in 6 months time.
