The Kia Rio is a car you can buy with confidence. As long as you search for one under 100,000 miles the seven-year warranty will keep you out of trouble. There are very few that will have done that mileage though.
There is very little evidence to suggest that the warranty is used much anyway, pointing again towards an extremely creditable car. As long as you don’t want to carry more than four passengers around, then it’s hard to find a case why you should go for anything other than this reliable, comfortable and relatively spacious car.
That is unless you need to have a better sized boot. That could be the deal-breaker here.
