What affects the price

Rental car rates shift based on a few main things. When you book matters most; securing a car weeks in advance is usually cheaper than walking up to the counter. The type of vehicle also changes the bill, as premium SUVs or luxury models cost more than compact sedans. Location plays a role, too, since airport taxes or urban parking fees can add to your total. Finally, adding extra drivers or protection plans will increase your daily rate. Exact pricing confirmed free on the call.
