First of all, congrats on looking for a new car! It’s good to see you’re doing your research, and you’re not wrong that Kia’s have above-average depreciation. Kia depreciation tends to be so high because they use cheap materials (like plastic instead of metal), have low labor costs, and have a short production line. Kia builds their cars to last 5 to 7 years, which doesn’t bode well for resale.
Kia compensates for their low depreciation rates with a much longer than average warranty coverage. In other words, even if you face mechanical issues with your Kia, you’ll have up to 7 years to bring it in for repairs.
