The bottom line
This model does not cluster around average. A big poor group sits next to a decent excellent-and-good share, with almost no middle, so the car in front of you is either worth keeping or a project. Start under the hood: cooling faults and engine oil leaks dominate, and transmission seepage shows up often enough to price in. Structural repairs hit 12 percent, three times the wider fleet, so any unibody or frame work is a walk-away unless a body specialist clears it and the price drops hard. Active codes on 46 percent of cars mean scan before you trust a quiet dash.
