Sort of like the car, but there have been a few issues with it.
£1600 warranty work to the clutch/gearbox.
Intermittent fault with the drivers door where it won't open from the outside.
Paint reacting with bodywork that the dealer steadfastly refuses to address as warranty. His first question was 'Where are your paintwork inspection documents from servicing?' My answer: 'I don't know, you carry out all the servicing, have you been missing work?'. Met with silence and a refusal to fix. Also claim it was stone chipping until I pointed out the lacquer wasn't holed, just the paint discolouring.
On that basis I wouldn't buy another.
There are a few niggly things too - like the interior light doesn't time out to switch off and it'll flatten the battery of the car. The interior is notably cheaper than other Kias in the range. Fuel economy and performance aren't great. Boot space isn't fantastic either.
On the plus side, it's nice to drive. Bags of interior space and easy to park, being mid way between Fiesta and Focus in size. It's also got a nice driving position being higher up that a 'standard' car.
Basically it's a fairly non descript car. Does everything reasonably but nothing spectacularly. It's pretty without being engaging in any way. It's not especially cheap to run either.
Would I buy another? No. I'd buy a Ford Focus petrol.
