You will find the car hire companies at Barcelona airport in both Terminal 1 and 2. The Car hire company in Terminal 2 is only in building T2B. Each of these companies is right next door to each other so you can be sure of cheap car rental prices.
You can try arranging your car rental directly with the companies but often internet based reservation services can give you a better price as they have negotiated discounts for bulk reservations.
