2006 Ford F-250 Super Duty XL 4dr Crew Cab SB (5.4L 8cyl 6M)
The 6.0 liter diesel is a nightmare. The Canadian ones seem to be fine, but the American ones have lots of problems. Batteries die, fuel injection problems, stuttering engine. If you're going to buy a warranty - purchase the Ford one only. We made the mistake of purchasing the dealership one and we've had lots of out of pocket expenses. I can't go two months without something going wrong.
