Hyundai's new Avante ranks as the most expensive car to repair among domestic compacts, a recent study shows.

In low-speed crash tests on 11 models released from 2010 to 2011 by the Korea Insurance Development Institute, the Avante MD was the most expensive car to repair, costing an average of W2.17 million (US$1=W1,127), the institute said on Wednesday.

The second most expensive model in this segment to fix was the Hyundai Accent at W1.86 million, followed by Hyundai's Veloster (W1.69 million) and i30 (W1.59 million), Kia's Pride (W1.46 million) and GM Korea's Aveo (W1.43 million). Kia's subcompact Morning cost W1.27 million to fix.

Among mid-sized models, the Hyundai i40 cost the most to repair at W2.26 million. The institute calculated costs after conducting front and rear-end crash tests against a wall at speeds of 15 km/h.
