For some of the plan options, there is coverage for engine and drive train listed as a covered item in the coverage schedule, but the term of coverage provisions exclude engine and drive train.
Some of the variances in the contracts can be attributed to varying state regulations. If I recall correctly, here in California these warranties must be purchased at the time you purchase or finance the vehicle. Additionally, the included and excluded coverage may also be dictated by regulation.
