Do they need a big car? Generally, the smaller the car, the cheaper it is to insure. So something like a Honda Jazz, Toyota Yaris or Ford Fiesta (with the 1.25-litre petrol engine) would be a good choice. If more space is required, a Skoda Octavia would be a good buy. It's very practical and insurance shouldn't be extortionate if they hunt out a 1.4 petrol. Shop around for insurance quotes - even without any NCB, it shouldn't be too expensive for a couple of their age. The 19-year-old son is likely to add to the cost, though.
