    Protect My Car Highlights 

    Protect My Car offers three different extended auto warranty plans for vehicles. The company also provides a comprehensive maintenance plan for older vehicles, which is why we gave it the Best Maintenance Benefits designation in our extended auto warranty industry review.

    CarShield Highlights 

    CarShield can be a smart choice for drivers on a budget, which is why we named it Best Value in our extended warranty review. The company offers six comprehensive plans that can protect your vehicle up to 300,000 miles. It is also one of the only top companies to provide coverage for specialty vehicles like ATVs and motorcycles.

    Protect My Car Vs. CarShield: Coverage

    In terms of coverage plans, CarShield offers drivers more choices than Protect My Car. We’ll break down different plan options from both providers below. 

    Protect My Car Extended Warranty Options 

    Protect My Car offers three basic levels of coverage to drivers, specifically targeting new and high-mileage vehicles. Here’s an overview of the different vehicle protection plans available: 

    • Supreme: This is the highest level of coverage offered by Protect My Car, and it’s designed for newer vehicles. The plan covers most car parts, and drivers only have to pay a $100 deductible for covered repairs. 
    • Select: This warranty coverage option is available for vehicles with more than 50,000 miles. The coverage plan protects most vehicle parts except the turbocharger and navigation. Drivers have to pay a $100 deductible for car repairs. 
    • Driveline: This plan protects vehicles four to 10 years of age with more than 80,000 miles. Drivers receive 5 years/125,000 miles of coverage, whichever comes first. Most major vehicle parts are covered in case of mechanical breakdown except the front and rear suspension, select brake components, the turbocharger, and the navigation. Drivers have to pay a $200 deductible for repairs. 

    In addition to these three vehicle service plans, Protect My Car also offers Ambassador Maintenance Plans for older vehicles, which are designed to reduce maintenance costs by 50 to 75 percent.

    CarShield Extended Warranty Options 

    CarShield offers six comprehensive plans for drivers to choose from, including two powertrain warranty plans, which Protect My Car does not offer. Here’s an overview of CarShield’s warranty plans: 

    • Diamond: This plan is similar to a new car warranty and protects all systems and components except those not explicitly mentioned. 
    • Platinum: This is CarShield’s best option for vehicles with higher mileage. It protects your vehicle’s engine, transmission, air conditioning, electrical system, starter, water pump, and fuel pump. 
    • Gold: This warranty plan offers enhanced powertrain coverage for your car’s transmission, water pump, alternator, starter, and air conditioning. 
    • Silver: This basic powertrain coverage protects your vehicle’s engine, transmission, and water pump. 
    • Aluminum: This specialty plan covers most electrical and computer-related systems, including the engine control module, starter, alternator, navigation/GPS, and electrical system. 
    • Motorcycle & ATV: This coverage option protects your motorcycle or ATV. 

    Additional Plan Benefits 

    In addition to the various coverage options offered by Protect My Car and CarShield, both companies also provide the following benefits: 

    Protect My Car


    Emergency Roadside Assistance

    Rental Car Reimbursement

    Courtesy Towing

    Trip Interruption Reimbursement

    Protect My Car Vs. CarShield: Cost

    Our team reached out to Protect My Car and CarShield to find out which offers more affordable bumper-to-bumper warranty coverage. The companies provided the following quotes for a 2018 Honda Civic with 30,000 miles and a $100 deductible: 


    Plan Name

    Term Length

    Monthly Cost

    Down Payment

    Total Cost



    5 years/

    70,000 miles


    for 18 months



    Protect My Car


    4 years/

    unlimited miles


    for 48 months



    Based on the pricing we received, CarShield’s Diamond plan is cheaper than Protect My Car’s Supreme plan for bumper-to-bumper coverage. Both companies offer monthly payment plans for most extended warranty coverage options.

    Note that you should use these estimates as a general idea for coverage since actual costs depend on multiple factors like the age of your vehicle, mileage, and where you purchase coverage.

The company also has better customer service ratings from the BBB, Google, and Trustpilot.

    Top Recommendations For Extended Car Warranties

    While both Protect My Car and CarShield ranked in the top five of our best extended car warranty providers, we recommend reaching out to Endurance and CARCHEX for warranty quotes as well. 

    Endurance: Best Coverage 

    Endurance is a direct provider, meaning it creates and backs its own plans. This differs from other companies that use an intermediary like a dealership to sell their products. Endurance warranty coverage plans include six levels of coverage that can last beyond 200,000 miles. The company also offers 1 year of Endurance Elite Benefits for free, which includes:

    • Roadside assistance 
    • Total loss protection
    • Collision discount
    • Key fob replacement
    • Tire repair/replacement
    • Endurance mobile

    Most drivers also find Endurance’s plan options affordable. A reliable car still under its factory warranty can get six years of exclusionary coverage for around $2,850, which is average compared with other estimates we received from third-party providers. Drivers can also choose from four different deductible plans.

    CARCHEX: Best For Used Cars 

    CARCHEX offers five warranty plans for drivers that can cover up to 250,000 miles, which is why we named it Best for Used Cars in our extended car warranty review. The company offers exclusionary coverage, high stated-component coverage, and several powertrain plans. 

    CARCHEX plans are affordable for most drivers. The company provided us with a quote of $2,570 for seven years of exclusionary coverage, which is average among top extended warranty providers.
