What we check for you
- The true total across rental companies, including airport charges, not just the daily rate
- Whether an off-airport branch nearby works out cheaper
- Young driver fees if anyone driving is under 25
- One-way fees if you're returning somewhere else
- Whether you can take the car across the border between the US and Canada
- Deposits and card holds, so nothing surprises you at the counter
- Which protection you may already have through your card or auto policy, and what to ask to confirm it
Want to check the rules yourself first? Read what you need to rent a car: licence, cards, deposits, age and insurance in plain English.
What we'll ask you on the call
Pickup and return locations, dates and times, how many people and bags, and the age of each driver. You don't need any of it to request the call.

Questions people ask
Do you book the car for me?
Your agent compares the options, tells you the real total and walks you through booking the right car. You decide before anything is booked.
Do you charge for help with a new booking?
The call and the advice are free. If you want your own agent for the rental, plans start at $25, and you hear the price before you pay anything.
Can you get me a cheaper price than the rental company's website?
We can't promise a lower price. We look for the discounts you already qualify for and the fees you can avoid, so the total is as low as it can be for your trip.
Pickup, drop-off, and everything in between. You've always got someone.
Planning a rental? Talk it through first
Tell us where and when. Your agent compares your options, spots the fees most people miss, and tells you the real total before you book.

If you already know what you want, you can compare prices from rental companies with Discover Cars on our compare prices page.
If you book through Discover Cars, we may earn a commission. It doesn't change the price you pay.
Prices are set by the rental companies and can change. Our job isn't to own the price, it's to find you the best available one, explain exactly what you're paying for, and stay with you until it's sorted. Where we can get you a better deal, we will.
OneCall Rental is an independent service. We're an affiliate partner of Discover Cars, and we're not affiliated with any rental company.
