Enjoyed car that was in decent condition but the shuttle bus was unpleasant due to broken a/c

There were only 2 people working the counter when I arrived. I waited in line for 15 min before it was my turn even though I was first in line. It took another 20 min for the person to try to upsell me to a larger vehicle, 4-wheel drive, GPS, insurance, etc. Then I had to wait another 30 minutes for my car to be ready. It apparently was the only mid-size car they have and instead of just upgrading me for free, I had to wait 30 min for them to wash, vacuum, and fill up the only Camry in their fleet. And they weren't exactly in a hurry.

Booking was easy. Not sure why the pricing changes so drastically from day to day but the price I paid was very good. There was no price drop this time after I made my reservation.

I did notice it until I was driving to my destination but the check engine light was on and remained on the whole time I had the vehicle. In addition the vehicle seemed to be out of gear even though it was an automatic that something could be wrong with the shifting or acceleration. I caused several minor scares throughout the time I had it.

The vehicle smelled like someone had smoked in it previously. It wasn't strong but still was offensive.

The wait at pick up counter was awful. I waited over 1 1/2 hours to Pick up a pre booked rental.
