      Arrived at the rental office around noon and completed the paperwork, but there were no cars in the parking lot. I was 10th in line and waited for over an hour, eventually getting a downgraded compact car. The staff said they would compensate with a full tank of gas. Considering California's high gas prices, it seemed fair enough, so I just took the car without making a fuss.

      The company billed me for the extra insurance even though I asked to decline it. They also hit me with an absurd $150 detailing fee after returning the car, even though the guy when I checked it back in said it looked good. All in all, my cheap rental ended up being more expensive than a premium car rental had I gone with a bigger brand company. Absolutely absurd. No one at Fox will respond to my emails or phone calls asking to escalate the issue up the chain. They sneakily had me sign a document adding insurance while quickly trying to finalize the booking after making me wait more than 30 minutes. I was behind one other person who was being helped when I walked in at around 10AM. Multiple other employees walking around the office, not doing anything substantial, and they just made me wait. When I finally get to the counter, I try and get through the process as fast as possible, and tell them I'm not interested in insurance as my personal car insurance will handle any problems. Then I somehow get billed an extra $100 for insurance over the duration of the trip. Absolute scam artists. I took the car to the beach. We ended up getting a small amount of sand in the carpet. When I turned the car back in, I asked if that was ok, and was told it wouldn't be a problem. Next thing I know, an added $150 detailing fee was hit on my card. There's a car wash at a gas station less than a block away from this car rental shop. I could have easily gone there, paid $20, and got the car washed and fully vacuumed out. If the guy had bothered to mention the detailing fee to me, I would have just done that and taken 10 minutes of my time and saved $130. Fox are scam artists. DON'T RENT FROM FOX

      They didnt have the Jetta so the guy downgraded my reservation instead of upgrading my reservation. (Playing Favortism) went back for the jetta the next mourning to yrade the car in since I had it for a week the jetta was there but had bad tags and this person upgraded me instead of downgrading me. Poor customer service Foxx. The first guy wanted a extra $70.00 at the time of booking or he was going to downgrade me for the same price I was being charged

      At the store, we upgraded to a Tesla Model 3. The staff at the store gave us a weekly discount, which was very cost-effective. The service was decent as well. The car was cleaned and delivered to us when we picked it up. The charging account was already set up. Renting a car in the US is still convenient and affordable.

      The wait time for pickup at the airport was about 30. Got to AVR it was almost an hour to get our van. We did not get the Kia that we rented. Olivia picked us up in a Dodge Durango. She informed us she did not have a van available we have to wait. We could have the Durango for an extra $10 a day I do rent a lot of vehicles when we travel they give us what they have no extra charge. She did have a van a dodge caravan she informed us it was dirty that we could have it if we wanted. We took it we did not want to wait any longer to get to our destination. The van was filthy inside and out looked like it wasn’t cleaned in a long time. She was very rude and did not know what she was doing. When we dropped off the van we had to wait the attendant was at lunch. She apologized and she dropped us off at the airport. She was very nice n apologized for the bad service we had when we picked up the van. She was very nice and sincere.
