Avis

Pros: nothing more than the other rental car have.
Cons: extremely bad customer service

I have rented a car before Easter in Budapest. First of all, it took 1 month to get the invoice. When I returned the car, they found a scratch on the back door (inside). I was surprised when I saw it as I was driving alone so for sure I didn't cause this scratch. No one was on the parking when I picked up the car and of course, there was one guy when I returned the car. As I am living in Sweden, the customer service in Hungary asked me to contact Sweden. Of course the office in Sweden doesn't know anything and say that what Avis Hungary says is the truth.
Are you checking each millimeter of the car when getting in ?
I have had other problems with Avis in the past so this is my last time buy at Avis, for sure!

Pros: There are no pros.
Cons: Costs twice the advertised price. 
Scammers for Customer Service.

To keep it short, my family went to florida on spring break. Rented from AVIS, didn't get the car we rented and had to rent a step up costing $100 more. Upon our return was charged $140 for having sand in the car. We went to the beach twice and each time showered our feet before getting back into the car...bottom line don't rent AVIS CARS. EVER.

Pros: Good car
Cons: Sneaky rental agents, sorry customer relations

I will not rent from AVIS again.
While on personal travel I rented and pre-paid for an AVIS sub-compact car. When I arrived at my destination, the rental agent told me that I was renting a compact car. Being tired, I didn't check that I was getting the car that I had paid for.

When I returned the car, the AVIS rental agent charged me extra for the compact car. I e-mailed AVIS customer relations about the extra charge and the ambush rental. Their stance is that I signed the contract and I owed them the money.

Pros: The car itself wa so-so.
Cons: They try harder--to tick you off.

The car itself was so-so.  The service was poor and slow at the counter.  Then I was overcharged for the car--the rate they quoted on my reservation was lower than the rate they charged when I went to pick up the car, which was lower than the rate they charged when I dropped off the car.  No one would listen to me when I complained.

Pros: NEVER USE AVIS AGAIN , RIP OFFS, NOT A BIG RANGE OF CARS
Cons: VERY SHOCKING CUSTOMER SERVICE AND VERY EXPENSIVE RATES.
NOT COMPETATIVE AT ALL. 

I AM VERY UPSET WITH AVIS'S CUSTOMER SERVICE AT MASCOT AIRPORT.
IVE BEEN WAITING TO GET SERVED FOR ALEAST 25 MINS CAUSE THERE WERE SO MANY PEOPLE INTHERE. PLUS WHEN I GOT THE VEHICLE I DROVE STRAIGHT OUT OF THE CAR PARK AND THE TYRE BLEW.
I WENT TO THE DESK TO GET HELP AND THEY SAID THEY WERE GOING TO CHARGE ME FOR A NEW TYRE.

Pros: sorry, but can think of no pros regarding service. Car was ok though.
Cons: They make money on customers by charging the whole refuelling even if not empty

Last time we used Avis, we paid 260 euros for 3 days ! that includes 140 euros for fuel !!! They forgot to inform us, that if we do not bring the car completely refueled they would charge us the whole fuel (even if it is full to 2/3rd for example) and they charge a service surchage and foreign VAT on top. It was not even a consuming  4x4, but a simple category B car.I will never ever use them again. Also baby car seat was not even installed in the car.

Pros: Car was fine
Cons: Overcharged for really bad customer support

Unfortunately my plans to learn Italian prior to my trip to Italy failed. Because of this, I arranged a reservation with Avis for an all-inclusive package (to include all necessary insurance) and was assured a desk agent and contract in English. When we arrived to pick up our car, we were informed that we did not have adequate insurance and that we would have to purchase additional at 20 Euro/day. Not wanting to ruin our trip because of a minor incident, we agreed to insurance. The trip was great and the car was fine. When I inquired about the insurance charges after we returned, I was informed that the insurance was indeed unnecessary, though since the blurry foreign contract was signed, Avis refused to issue any sort of refund, despite their acknowledgement that this was unnecessary due to either the desk agents mistake or an outright unnecessary upsell. There has been no response from Avis's Italian branch in attempt to allow them to rectify the situation.

Pros: none
Cons: Will not honor priceline agreement, and charge almost $10.00 a gallon to fill it up.

I travel eight to ten times a year and deal with rental car companies all the time.  Yes, they are all a pain to deal with but you expect that.  It is something else when they blow you away with being hard to deal with.   I got a priceline deal with avis and at the counter the manager refused to recognize price for the agreement.  Then they charged me $65.90 to fill up the car which I returned 3/4 full.  I don't usually write these reviews but people need to be warned about avis car rental.  It is worth paying more and dealing with a reputable rental car company.

Pros: Selection of cars
Cons: Too many hidden fees, Enterprise is Much cheaper and more bang for your buck.

My estimated charge was $93.15, but my final bill came out to be $316.35.  Here is a break down of my charges ...

3 days @ $26.99 = $80.97

below is the extra/hidden fees (beware!)
$0.47/DY ERF = $1.41
** 11.11% FEE = $14.98
LDW = $83.97
FTP SR $0.75 DY = $2.25
$3.00/DY CFC = $9.00
TRANSP FEE = $4.49
$2.25/DY VLF = $6.75
~~ SUBTOTAL (so far) = $203.82 ~~
TAX 15.000% = $30.57
FUEL SERVICE = $38.49
PAI/PEP/ALI CHG = $43.47

TOTAL $316.35

OUTRAGEOUS!!!  This is my first time renting from AVIS and will be my last time.  I usually rent from Enterprise and my average rental charge for Enterprise, with the same size car and same # of days plus insurance/damage/collision, is usually around $180.00.  AVIS is too damn expensive with too many hidden fees!!
