Diamond Warranty vs SilverRock

Diamond Warranty is a Pennsylvania-based vehicle service contract provider founded in 2006. Operating through a nationwide network of dealerships, they offer several levels of protection designed to help drivers manage repair expenses after factory warranties expire. Their plans range from basic powertrain coverage to broader exclusionary contracts, with options for used vehicles, certified pre-owned models, and drivers seeking long-term protection.

Many contracts are backed by AmTrust Financial Services and may include benefits such as roadside assistance, rental car reimbursement, and trip interruption coverage. The company focuses on dealer-distributed service contracts rather than direct online sales, which means pricing and contract details often vary by vehicle and dealership. Diamond Warranty maintains an A+ rating from the Better Business Bureau, though they are not BBB accredited.

Customer feedback across review platforms is mixed, with experiences ranging from praise for responsive representatives and straightforward claims to complaints involving coverage disputes and communication challenges. With nearly two decades in the industry and a diverse selection of plans, the provider offers several features worth examining more closely before making a decision.

SilverRock is a vehicle service contract administrator founded in 2014 and headquartered in Phoenix, Arizona. Rather than selling extended auto warranties directly to consumers, they administer protection plans for vehicles purchased through retailers such as Carvana and DriveTime. Depending on the contract, customers may receive a limited warranty, an optional vehicle service contract, or both, with coverage for many major mechanical and electrical systems. Many plans also include benefits such as roadside assistance, rental reimbursement, transferable coverage, and access to a nationwide network of participating repair facilities.

One feature that distinguishes SilverRock is their close integration with the vehicle buying process. Eligible customers can often add protection when purchasing a vehicle, and participating repair shops can work directly with SilverRock during the claims process. Pricing and contract terms vary based on the retailer, vehicle, and selected coverage, so there is no standard published price.

Customer feedback is mixed across major review platforms. While some policyholders report smooth claims and substantial savings on expensive repairs, others describe claim disputes, communication issues, and inconsistent service experiences. This review takes a closer look at SilverRock's coverage options, contract terms, costs, customer experience, support resources, and overall value to help determine whether their vehicle protection plans are worth considering.
