If this is the 1600 cc engine, yes, the starter can only be reached by one hand at a time from under the car, which makes it pretty hard to test safely in situ ... absent a proper tester/analyzer. So... I'd start by making sure the battery is fully charged and connections clean and tight. If you can get the car somehow to an auto parts store that does electrical system testing for free, they can tell you whether the starter is bad.
