- Power Train — 2 owner reports. Test-drive through all gears, including reverse; note slipping, harsh or delayed shifts.

- Mileage to watch. Owners typically reported problems around 10 miles; ask what was repaired near that point.
- Before you pay: service records, a history report and an independent inspection.
