Mostly fine but leaking gas when refilling super dangerous.

I originally booked the car for 10 days, but returned it 4-5 days early, and they didn’t refund me anything.

I reserved a Tesla and was offered a Hyundia and a Mercedes. Hyundai is not the same class of vehicle. The Mercedes software was in beta stages. Lane keep assist would bounce around the lane even leaving it, it was if a drunk driver was driving. Navigation system failed 80% of the time either couldnt' find the location like Leogo land for instance but could find Legoland Holiday Inn. 4 out of 5 charging locations it directed me to were behind locked gates. Charging port wouldn't open and required 20 minutes with another Merc owner to figure out. Regenerative braking would simply give up by design at 20Km/hr in other words stop breaking coming up to another car at about 3 car lengths away nearly causing an accident. Later if stopped at about 80km/hr. The car a is a disaster and would stop anyone from owning an EV if they didnt' know better. AVIS customer support was useless. They told me to drive back to the airport to talk to the front desk about changing my reservation. I asked why would i spend a 4 hour round trip driving instead of talking ot them on the phone to confirm they had a car available. This was not possible apparently as they are to busy for existing customer to pickup. I was obviously annoying the CR asking such questions. Upcharged for Tolls. I was told I would go through a ton of tolls on my trip at least 10-15 and that I should purchase the flat toll fee. I went through two. A roughly $20 charge was turned into $70. Upcharged for charging. Asked how much I thought I was going to spend charging the car up before drop off convinced I should spend $20 to charge it at drop off. The Merc comes with Free 30 minute charging more than enough to charge the car to full. Further lies.

The attendant's service attitude was quite good.

The service attitude was great.
