The reliability of Mazda 3s has been above average. However, after a 13 year old vehicle's future reliability depends in part on how well it was maintained. Find a maintenance schedule for this year 3 and question the current owner to ascertain whether recommended maintenance was done. Copies of receipts or a detailed record are desirable.
