While the Skoda Kylaq is an altogether nicer package than the Citroen C3, we wouldn't wholeheartedly recommend buying a test drive vehicle. These cars are driven by prospective buyers of different skill levels and can show accelerated wear as a result. Test cars also often pick up dings and damage over drives, so it's best to avoid them. You could consider a customer pre-owned example instead.
That said, the C3 Turbo AT is a fine city car. It's got a great engine and gearbox combo, and ride comfort is also impressive. Citroen has also done well to spruce up the C3's cabin. Citroen's service network isn't very widespread, but if you have an outlet close by, the C3 could be a good pick for your father.
