안됩니다. 
가능할 것 같습니다. Priceline이나 Autoslash도 Car Rental Agency라고 볼 수 있으니까요. 확실히 하시려면, 체이스에 문의하시는 것이 제일 좋겠네요.

CSP Benefits Guide page 4에 보시면 다음과 같습니다. 

What’s Not Covered? The Auto Rental Collision Damage Waiver benefit does not apply to: •  Any obligation You assume under any agreement (other than the deductible on Your personal auto policy) • Any violation of the auto rental agreement or this benefit •  Injury of anyone, including you, or damage to anything, inside or outside the Rental Vehicle • Loss or theft of personal belongings • Personal liability •  Expenses assumed, waived or paid by the auto rental company or its insurer •  The cost of any insurance or collision damage waiver offered by or purchased through the auto rental company •  Depreciation of the Rental Vehicle caused by the incident including, but not limited to, “diminished value” •  Expenses reimbursable by Your insurer, employer, or employer’s insurance •  Theft or damage due to intentional acts or due to the driver(s) being under the influence of alcohol, intoxicants, or drugs, or due to contraband, or illegal activities • Wear and tear, gradual deterioration, or mechanical breakdown • Items not installed by the original manufacturer • Damage due to off-road operation of the Rental Vehicle •  Theft or damage due to hostility of any kind (including, but not limited to, war, invasion, rebellion, insurrection, or terrorist activities) • Confiscation by authorities • Vehicles that do not meet the definition of covered vehicles •  Rental periods that either exceed or are intended to exceed thirty-one (31) days • Leases and mini leases •  Theft or damage resulting from the authorized driver’s and/or cardholder’s lack of reasonable care in protecting the Rental Vehicle before and/or after damage or theft occurs (for example, leaving the car running and unattended) •  Theft or damage reported more than one hundred (100) days* after the date of the incident •  Theft or damage for which a claim form has not been received within one hundred twenty (120) days* from the date of the incident •  Theft or damage for which all required documentation has not been received within three hundred sixty-five (365) days after the date of the incident • Vehicles that are not rented from a Rental Agency•  Damage to the interior bed of a pick-up truck unless such damage is caused by or the result of a covered loss, such as theft or collision •  Damage to a pick-up truck that is a result of loading or unloading objects into the bed

4년전이지만 사프로 익스피디아에서 빌린 차 힛앤런 아무런 문제없이 해결했습니다. 

아멕스의 경우는 아멕스랑 채팅해서 렌트카 보험 커버 된다는거 확인 했습니다. 

이미 다른 분들의 말씀처럼 Turo 같은건 안되고 오토슬래쉬로 연동된 일반적인 렌트카업체/여행싸이트는 됩니다.

댓글 달아주신 모든 분들 정말 감사드립니다. 많은 분들이 된다고 해주셨네요! 하저씨님께서 추천해주신 대로 체이스에 최종 문의 해보고 답을 얻게 되면 공유차 글 업데이트 하도록 하겠습니다.

묻어가는 질문인데 샤프로 체이스몰에서 UR포인트로 렌트카 예약하면 보험 커버되는거죠?
