No upselling, but the car given was too small. I booked a Renault but got a Kia hybrid, not sure what model. With 5 people and 5 suitcases, it couldn't fit anything else. Considered getting a bigger car, but the price doubled, so I decided against it. Spain really requires small cars; navigating old town streets and even regular parking lots is a test of driving skills and judgment. Another issue was that the trunk couldn't lock, not sure why. Remember to send the address when picking up the car; just head to the car rental parking lot. There was a traffic ticket and toll fee from Portugal; not sure how much of the deposit will be refunded.
