Sounds like it may well be a fantastic buy at 5 years old (when you'll probably pick it up for 30% of the new price).
Co-incidentally my SIL's 6 year old Kia Sportage has had a no quibble turbo changed under warranty even though it hasn't been serviced at Kia since it was 2 years old (none of the subsequent service invoices from her local garage specified the oil spec used, only the weight) - impressive service...
