Entry-level SE editions get a generous standard kit list, which includes 16in alloys, air-conditioning, electric windows all round and a auto-dimming rear-view mirror. Stepping up to SE-L gets you dual-zone climate control, automatic xenon headlights, rain-sensing wipers and rear parking sensors.
SE and SE-L are both also available as SE Nav and SE-L Nav, which add satellite navigation to the abilities of the infotainment system. The upgrade isn't that cheap, though, so you'll need to be sure you need integrated navigation before stumping up the extra.
The range-topping trim level is called Sport Nav; it brings larger alloy wheels (18in), front parking sensors and keyless entry, although you'll still have to pay extra if you want leather seats.
