I used to have a Kia Sportage and the missus has a Hyundai i30. Kia are a Hyundai group company but offer 7yrs compared to 5yrs for the parent company..never understood that!
The Kia dealers were great for me and the car very reliable. Some parts were restricted to main dealer, but if buying new that's not really an issue.
It's all in house Hyundai group. The platform will be shared with other compact group cars - possibly Hyundai i20. The engines are similarly offered across the range. The 1.6 diesel is the one that my wife has in auto form in her i30 and it does a good job - genuinely. It doesn't have the highest output or the latest tech but is a good all rounder.Is the Soul based on the chassis of another car, is the engine from another manufacturer, or any other salient points I should be aware of.
I would have zero concerns buying a new Kia whatsoever.
