Ace Rent a Car Denver location basics

Ace Rent a Car operates a Denver location that serves both airport and local rentals, though the company is smaller than the national chains like Enterprise or Hertz. The Denver branch handles standard vehicle categories — economy cars, mid-size sedans, SUVs, and vans — but availability and pricing shift with season and demand. You'll find the location at Denver International Airport (DEN) and also have the option to rent from an off-airport Denver address, which sometimes costs less per day.

Ace is a franchise operation, meaning individual locations set their own policies on things like damage waivers, fuel options, and late fees within corporate guidelines. The Denver location's specific rules on these points may differ from another Ace branch in another state. Before booking, confirm the exact pickup address and hours with the location directly, since airport and off-airport branches keep different schedules.

Key Takeaways

  • Ace Rent a Car Denver has both airport and off-airport locations, with off-airport rentals often costing less per day than airport pickups.
  • You will need a valid driver's license, proof of insurance, and a credit card at pickup — some locations accept debit cards but require additional documentation.
  • Damage waivers and fuel policies vary by location, so confirm what the Denver branch charges for collision coverage and whether you can return the car with a full tank or pay per-gallon rates.
  • Late return fees and mileage limits depend on your rental agreement, so read the terms before you book to avoid surprise charges.
  • Ace's rates are often competitive with larger chains for short rentals, but comparison shopping across multiple companies for your exact dates usually saves money.

What documents and payment methods you need at pickup

Ace requires a valid driver's license (U.S., Canadian, or international with an English translation) and a major credit card in the renter's name at the time of pickup. The credit card is used to place a hold for the rental cost plus a damage deposit, which typically ranges from several hundred to over a thousand dollars depending on the vehicle class. If you arrive with only a debit card, the Denver location may still rent to you, but expect to provide additional forms of ID, a utility bill showing your current address, and sometimes a return airline ticket or hotel confirmation.

Proof of insurance is not always required by Ace itself, but your own auto insurance policy or a credit card's rental car coverage can reduce what you pay for damage protection through Ace. Bring your insurance card or a declarations page from your policy to show the rental agent. If you decline Ace's collision damage waiver and rely on your own coverage, you remain responsible for the full cost of any damage until your insurance processes the claim — Ace will still charge you upfront.

Damage waivers and what they actually cover

Ace offers a collision damage waiver (CDW) or loss damage waiver (LDW) at the Denver location, which shifts responsibility for most collision and theft damage to Ace rather than to you. The daily cost varies but typically runs $15 to $30 per day depending on the vehicle size. This waiver does not cover damage from off-road driving, racing, mechanical failure, or damage caused by driving under the influence — read the specific terms for the Denver location before you book.

If you decline the waiver and damage occurs, you pay the full repair cost or the vehicle's replacement value if it is totaled. Some credit cards (American Express, Visa Signature, Mastercard Premium) include rental car coverage that may cover collision damage if you charge the entire rental to that card, but coverage limits and exclusions vary by card issuer. Call your card issuer before pickup to confirm what is covered and whether you need to decline Ace's waiver to set up the card's coverage.

Fuel options and how to avoid overage charges

Ace typically offers two fuel options at pickup: a prepaid full tank (you pay upfront for a full tank at a set price per gallon, usually higher than local gas station rates) or a pay-as-you-go option (you return the car with whatever fuel remains, and Ace charges you for any missing fuel at their per-gallon rate, which is often significantly higher than retail). The prepaid option is usually cheaper if you plan to use most of the tank, but you forfeit any unused fuel — Ace does not refund the difference.

To avoid overage charges, return the vehicle with a full tank if you chose pay-as-you-go, or confirm the exact location of the fuel pump and the grade of fuel required before you leave the lot. Some renters find it cheaper to fill up at a gas station near the return location 10 to 15 minutes before returning the car, rather than paying Ace's per-gallon rate. Ask the agent at pickup which option costs less for your expected driving distance.

Mileage limits and overage fees

Ace rental agreements at the Denver location may include a daily mileage limit (often 100 to 150 miles per day, depending on the agreement) or unlimited mileage. Check your specific rental contract before you drive away. If your agreement includes a limit and you exceed it, Ace charges a per-mile overage fee, typically 25 cents to 50 cents per mile, which can add up quickly on a longer trip.

Unlimited mileage agreements usually cost more per day but make sense if you plan to drive more than 150 to 200 miles daily. For a weekend rental in the Denver area with local driving, a limited-mileage plan may be cheaper. Compare the daily rate difference between limited and unlimited options for your specific rental dates and expected mileage before you book.

Late return fees and extension policies

Ace charges a late return fee if you bring the car back after the agreed return time, typically $50 to $75 for the first hour and additional hourly or daily charges thereafter. The exact fee structure depends on the Denver location's policy. If you realize you will be late, call the location as soon as possible — some branches will extend your rental for an additional day's charge rather than explore late fees, but this is not may provide.

If you need the car longer than your original agreement, it is usually cheaper to extend the rental before the return time than to pay late fees. You can often extend online or by phone, though availability depends on whether another customer has booked the vehicle for the next rental period. Plan your return time conservatively, especially if you are returning to the airport and need time to check in.

How Ace's Denver rates compare to other rental companies

Ace's daily rates for economy and mid-size cars in Denver are often 10 to 20 percent lower than Enterprise, Hertz, or Avis for the same vehicle class and dates, particularly for off-airport pickups. However, the final cost depends heavily on what you add: damage waivers, fuel options, and airport facility fees can easily double the base rate. A $30-per-day economy car can become $70 or $80 per day once you add a collision waiver and choose prepaid fuel.

The best way to compare is to enter your exact pickup location (airport or off-airport), return date, and vehicle class into Ace's website and at least two other rental companies' sites, then note the total cost including all mandatory fees and your chosen options. Ace often wins on base rate but may not on total cost if you need comprehensive coverage. For one-way rentals (picking up in Denver and returning elsewhere), Ace's rates may be higher because the company has fewer locations to balance inventory.

Frequently Asked Questions

Can I rent from Ace Denver if I am under 25?

Yes, but Ace charges a young driver surcharge (typically $15 to $25 per day) for renters under 25. Some vehicle classes may not be available to drivers under 21. Confirm the surcharge amount and any vehicle restrictions for your age when you book, since these vary by location.

What happens if I get into an accident and I declined the damage waiver?

You are responsible for the full repair cost or replacement value. Ace will charge your credit card when ready, and you then file a claim with your own auto insurance. If your insurance denies the claim or pays less than the damage cost, you remain liable for the difference to Ace.

Can I pick up at the airport and return to the off-airport Denver location?

This depends on Ace's current one-way rental policy at the Denver location. Some branches allow it for an additional fee; others do not. Call the Denver location or check the booking page to confirm whether one-way returns between the two locations are available.

What if the car breaks down while I am renting it?

Call the Denver location when ready. Ace provides roadside information and will arrange a tow or replacement vehicle. You are not responsible for mechanical failure unless you caused the damage through misuse. Keep the location's phone number in your phone before you leave the lot.

Do I need to buy insurance from Ace if my credit card covers rental cars?

Not necessarily, but confirm your card's coverage limits and exclusions first. Some cards cover collision but not theft or liability. If your card's coverage is limited, buying Ace's damage waiver may be worth the cost. Read your card's rental car benefits document before you decide.
