Which used Kia Rio hatchback should I buy?
We'd go for the diesel. The 96bhp 1.4 petrol is cheaper, and it's fine in town, but it gets noisy at speed and isn't strong enough to cope with steep hills without changing down a gear or two.
On the other hand, the 109bhp 1.5-litre diesel pulls strongly, and overtaking is easy. It makes more financial sense, too. You won't find a cheaper diesel-powered car of this size, and its fuel economy is also far superior to the petrol's.
Of the two trims, we'd go for the range-topping LX. You'll get alloy wheels, air-con, remote central locking, four electric windows, six airbags and a CD player. The upgrade isn't that pricey, either.
The more modest GS is missing too much safety kit on the petrol-engined car (no curtain airbags), although you do get air-con, powered front windows and a CD player, though. Oddly, the GS diesel is better, with curtain airbags, a sunroof and electric rear windows added.
