Car hire at Denver Intl Airport

Pros: Tried to give me a car with no license plate and then told me "dont worry, they're not pulling people over because of COVID-19." More hidden fees than a flim-flam snake oil salesman. A $131 "deal" rental turned out to be over $450 after fees and surcharges. I'll ride a bike before I rent from ACE again. An absolute nightmare. The agent at the counter was more worried about the shoot-em-up game on his cell phone than taking care or me. Avoid ACE at all costs.

Pros: easy drop-off.

Cons: Ace is a low new, low budget organization and it shows. We rented a car for a few days as our vacation was affected by Corona Virus issues so we diverted from one location to another. Long story short we extended our vac a few more days so I called Ace to extend and they charged a daily fee that was double the normal rate. They gave a car that was filthy inside and out so I had reservations whether to take the car fearing that upon return they would charge for the filthiness. When returning the car we decided to pay with another credit card from the one that the car was reserved with - several days later redundant charges were on both credit cards and were not reconciled until I called to remove the double charges - makes me wonder what would have happened if I did not verify and call to reconcile charges.

Cons: The hours were confusing, and with our later arrival flight, we were relieved the airport shuttle still came around for us and a few other flyers. The hours posted mention 7pm as closing which was cool that the office was still running around 730 pm, but the confusing hours definitely stressed us out running through the airport with luggage. There was even a group of people behind us in the office line at almost 8pm. If you have a flight outside of 7am - 7pm, this wont work out very well. There's a FINE Car Service down the road if you need to return your car outside these hours, but Ace doesn't tell you upfront. Luckily, one return agent outside told us about FINE and although we had to pay $31 fee instead of the $25 he mentioned, he felt the most honest of the whole experience here. The part most disappointing was the price advertised on Kayak ($28) and what we ended up paying at the rental office ($500+). We had already figured in car insurance in our pre-arrival budget planning, but with the rush/pushy sales transaction from our Agent, we didn't get a chance to really figure out our options. Way too many hidden costs and up-sells. We were up-selled a toll fee we probably never used during our week-long trip (at least we didn't see any active Toll signs and we'd been looking for them specifically due to the up-sell) and adding a 2nd driver is NOT free like most other car rental companies. What was worse was after we wanted to remove the 2nd/backup driver to save at least something, our sales agent said the transaction already went through and nothing could be done about it. Since other goods-and-services can be returned and we hadn't even gotten the car, it sucked to believe we couldn't remove that 2nd backup driver. Being exhausted and already rushed, we pretty much gave up and just wanted to get on the with driving to our hotel. If you're from out-of-state like us, you're better off with an agency like Enterprise that's more clear with what you're getting.

Cons: I only learned, when going to pick up the car, that I was not supposed to take it outside the Denver area. I was finally able to do that, after agreeing to an insurance policy that cost me more than $100 extra. I was also told I would save money by paying for a tank of gas, when in fact I needed about half of that. I ended up paying about 2 1/2 times what I'd originally expected to pay.

Pros: All the staff I encountered were friendly.

Cons: A number of concerns. The car that I was given had a low pressure warning on one of the tires, I was told to “take it around back“ and get air put in and when the warning was off to go back through the exit. Looking back this should’ve been a warning sign and I should’ve just asked for a different car, but I followed the instructions and once air was put in the tire the alert went off. The tire obviously had a leak as the alert came back on the following day and I spent all three days in my rental trying to find a place to keep air in the tire. However, This is not the biggest frustration with the ace rental car process at the Denver airport. Be aware if renting from them that their hours of operation are 7 AM to 7 PM. If you return your car outside of those operating hours there is a $25 charge to drop it off at a different location down the road from their offices. This $25 charge was not listed, or at least not listed clearly, during the time of reservation. It basically feels like $25 was stolen from me. If you have an early morning or evening flight, beware of this extra charge. I did not utilize the shuttle back to the airport after dropping off my car, and requested that the fee be waived, and was told that that was not possible. I booked through this company because the price was so much lower, but after the extra charge, I should’ve just gone with a more reputable rental car agency And paid the money to get a better quality of car and not deal with these types of shady practices.
