Book Avis car rentals in London

Cons: I will never use Avis again - ever. In Jan 2019 I booked a car for pick up at LHR Dec 16, making the mistake that my flight out of SFO was actually getting into LHR Dec 17. Had I picked up the car Dec 16, I would have been paying $460 for my rental period. With zero flexibility they wanted me to now pay £2000 for the same rental package (1 day less in fact). After a long haul flight with 4 biggish bags - which the Avis shuttle driver gave no help with - I had to go back to T2 and get a car from National for £600. Same size as my original Avis booking, help with baggage into and off of bus and even into my car! Enterprise rocks. Avis sucks big time.

Cons: I made the mistake of not bringing my passport to the rental counter. Although not explicitly stated anywhere in the terms and conditions, a passport for foreign tourists is required to rent a car from Avis Heathrow. A driver's license is not sufficient documentation.

Pros: The staff seemed nice, but didn't inform you of extra things (like paying extra for wifi or navigation which are standard in all cars now). Also signage to get to location is HORRIBLE in the airport + no employees of the airport really know how to tell you to get there.

Disapointed

Pros: Car was clean inside.

Cons: Night time flight tried to reduce the hassle of insurance early in the a.m. Made reservation on line with car rentals .com for a Hyundai -I 30 at he same time I purchased the collision damage coverage. This was through Allianz insurance. At check in at Avis they would not accept this insurance, they allowed me to call Allianz in the US their rep was helpful and was sorry the insurance was not accepted, a refund was offered and accepted. Bottom line I wound up paying about $ 100 more for this rental. And the car supplied was smaller than the model I requested.

Cons: I was inadvertently upsold to a more expensive rental than I had reserved on line. The end price was almost twice as much. I will need to strategize how to avoid that in the future if I look at renting from Avis again.
