Most definitely take your cell phone out and photo your rental when you receive it and after you’ve driven it and returned it.
Before I ever leave a rental car facility I’ve done that. I’ve also made sure the radio, heater/AC works, the seat is adjusted, brakes work, checked where the spare is located, and asked for an emergency number ( I always use Hertz and want a local number as well. If there’s a business card I’ll grab it.)
On one sojourn to the Cotswolds from Heathrow my new ( said on 12 miles on the odometer) when I left the N. Perimeter Road at LHR. Long story short the clutch gave out ( and do not try to blame me. Learned on a clutch and have a Jeep with one). Called Hertz from where I was staying in Winchcombe and they made arrangements for me to ride along as the vehicle was towed to Cheltenham and then to be dropped off at a teeny Hertz office where I was the only customer and got the only rental there.
It worked out brilliantly and Hertz did not charge me for the original rental and gave me the lowest price on the replacement vehicle.
Hertz Gold Membership is worth it IMHO.
