It's good that it didn't snow, otherwise this car model wouldn't have been suitable.

1. Forced insurance purchase

2. Additional toll fees

These two issues caused the actual price to increase significantly.

The store explained that Colorado state law requires additional insurance.

Also, extra toll fees were added, with two options: $15 per day or $10 per day for actual toll charges.
Due to the time it would have taken to contact the rental car company, I had to reluctantly accept these charges.
Waited about half an hour to pick up the car.

Overall quite good

I personally use this car rental company both in Germany and the USA. The service quality is top-notch, with no additional sales or imposed services. The car return and inspection process is fast and efficient. The cars are new and in good condition, with full fuel tanks.

Only 1 driver allowed. I had called to confirm we could have 2 drivers. One tire was really low on air. Thrifty would not fill up. Previous renters trash was still in car

Like: The rental agents were all friendly, helpful, and the price for our rental was excellent.
Dislike: The car was just ok. I had never driven a Nissan Sentra and was disappointed with the performance. I picked the car, so that is on me. The interior of the car was not very clean.
