Tried called Amex PCR and didn't get a straight answer. Read through printed plan documents, didn't mention such a scenario...but it seems like it would just cover the deductible, whatever that may be?

---
So I have Amex PCR on my AmexPlat and will soon rent a car in Mexico. The company has insurance on the car but with a (possible) deductible of 10%, which could amount up to $2,000 or so if the car was a wreck. (VW Jetta / Kia Forte) So my question is, will Amex PCR then just cover this deductible if this was the case? But I would prob have to pay the deductible with the card before leaving and get reimbursed?

Ten Car Rentals in Cabo Airport. I rented from them earlier this year w/ o incident thinking it was totally covered or mostly, but took a closer look now and it's bit confusing. Says both 0% deductible, and 10%, and 5% for theft. Have reached out to company for clarification.

https://tencarrental.com/no-worries-protection-program/LDW – 0% deductible in case the car is lost: This coverage eliminates every responsibility for damages, or total or partial theft. This coverage will be annulled if terms and conditions agreed when this rental contract is signed are not complied; this protection does not include loss or damage of keys, license plates, fines and/or cranes.

CDW – It is a coverage that reduces payment responsibility in case or total or partial damages caused to the leased motor vehicle, with a deductible of 5% over the value of the car, which will be applied when damages are higher than the deductible stated for collision. In case damages are lower than the deductible, the total value of the damage caused will be charged.

TP – Protection against Theft: This protection partially releases the lessee from responsibility for total or partial loss of the vehicle caused by theft. All our vehicles are insured against total theft paying only a deductible of 10% of the total value of the car.
