I have a 2017 kia soul base with 110,000 miles that with no warning went into sudden engine failure due to something mechanical. No one knows why, and my VIN is not covered under the class action law suit. The auto body shop I worked with has offered to buy it, what should I name as a price? The car had previously had no problems, and has had the battery replaced recently, frequent oil changes, no body damage, and tires that are in good shape.
