Final answer:
Stacy's car insurance policy will cover the repair cost of $1,575 minus the $100 deductible for Mechanical Breakdown, making the total payment from the policy $1,475.00. The tune-up cost and the excess towing cost are not covered by her policy.
Step-by-step explanation:
In assessing Stacy's claim, we need to consider the terms of the Mechanical Breakdown coverage. The policy indicates that the Mechanical Breakdown coverage has a $100 deductible and is valid for 12 months or 12,000 miles, whichever comes first. Since Stacy purchased the vehicle on 10/1/2005 and the breakdown occurred on 9/25/2006, the coverage is still in effect, being just under the 12-month limit.
Now, considering the costs, Stacy's policy will not cover the $200 tune-up as it's a maintenance expense, and the towing cost should be covered under the Towing and Labor coverage up to the $75 maximum limit. However, the breakdown repair costs $1,575, and with the presence of a $100 deductible for the Mechanical Breakdown coverage, Stacy needs to pay the first $100. Therefore, Stacy's carrier will pay for the repair after the deductible, which is $1,575 - $100 = $1,475.00.
